A bloke in the corner called Kierkegaard, biting the heads off whippets...


Day 73  

General status update

Hair: bracing itself for FEC4, but looking forward to the snood

Nausea demon, Chemo Muse, Chemo Brian: back from their trip - to Whitstable, as it turns out - where the weather was lovely, they stayed in a designer B&B, and a wonderful time was had by all. Excellent. So happy they’re all BONDING.

Anxiety level (1-10): see dread

Dread: see below

State of mind: see dread


“Like one, that on a lonesome road Doth walk in fear and dread, And having once turned round walks on, And turns no more his head; Because he knows, a frightful fiend Doth close behind him tread”
Samuel Taylor Coleridge, The Rime of the Ancient Mariner, 



  
The 19th Century Danish existential philosopher and theologian Søren Kierkegaard, or ‘the Danish Doctor of Dread’ as the New York Times recently described him, distinguishes between fear and dread: he argues that fear is the emotional response humans experience in response to some known potentially harmful or dangerous object or situation, as when facing a wild animal, or in a potentially embarrassing situation, such as public speaking.

Dread, on the other hand, he defines as unfocused fear, in relation to freedom, and the anxiety of choice: using the example of a man standing on the edge of a cliff, knowing that he could throw himself off it, and decide his own destiny. This realisation, that one has the possibility and freedom to do something, even the most terrifying of possibilities, is dread: the ‘dizziness of freedom’.

Kierkegaard so didn’t know what he was talking about.

Try a few cycles of chemo, Søren, and then you’ll be able to distinguish very clearly indeed between fear and dread. Fear can be of the known, but the greatest fear is of the unknown, because the very fact of something - say your first dose of chemo – being an unknown quantity means that your imagination runs wild. When what you fear is unknown, your fear knows no bounds, and the night before my first dose of chemo I was very scared indeed.

Tonight is the night before my fourth dose of chemo, and I’m no longer feeling fear, as I know now exactly what will happen to me, and just how bad it will make me feel, particularly between days 5 – 10 after I receive the chemotherapy. I don’t feel fear anymore – what I feel now is dread, and it’s getting to be much worse than the fear ever was. Every time I think about the chemo ward and what will happen to me there I shudder, and my stomach turns over, as well it might, since it is my stomach that bears the brunt of the side effects both of the chemo, and of the drugs they give to help with those side effects.

There’s another name for this: they call it ‘anticipatory nausea’:

“Many patients who experience nausea and vomiting as a result of chemotherapy
develop a preceding wave of symptoms, known as anticipatory nausea and
vomiting (ANV), before starting their subsequent cycle.

Nearly one in three patients experience anticipatory nausea, while anticipatory
vomiting occurs in about one in 10, according to the National Cancer Institute
(NCI). Unlike post-chemotherapy nausea and vomiting, however, which can begin
hours to days after treatment in reaction to drug effects on the gastrointestinal
tract, ANV shows up before treatment. Symptoms are generally experienced
among those whose nausea and vomiting were not controlled by medication or
other measures after prior chemotherapy sessions.

ANV is thought to be a result of classical psychological conditioning. The sights,
sounds and smells of the chemotherapy room, with oncology professionals
milling about, take on new significance once chemotherapy treatments begin.
These previously neutral stimuli then prompt a learned response from patients
once they begin to associate this setting with nausea and vomiting, and this
response becomes a pattern.”

I first realised I was suffering from this last week, when someone with the very best of intentions sent me a cheery video of a young woman with cancer dancing around and singing ‘What doesn’t kill you makes you stronger’ -  in a chemo ward. It was her way of putting two fingers up to chemo, and to cancer, and it was lovely, but I couldn’t watch it for more than a few seconds, because the images of the chemo ward, the machines, the plastic bags of chemo drugs on the drips, immediately made me feel ill: my stomach churned.

Even thinking about it now makes my stomach churn – and it reminds me of the film A Clockwork Orange, where the aversion therapy given to the brutal, vicious protagonist Alex - watching violent films after being injected with drugs which produce extreme nausea - not only makes Alex feel extremely ill when he thinks about violence, but also when he hears the music of Beethoven, which was played along with the films.

I have now become, like one of Pavlov’s dogs, or Alex, psychologically conditioned to respond to other cues besides the chemo drugs that actually induce nausea; just the sight of a chemo ward on that YouTube video evoked an instant, visceral response. This is a bit of a worry, as I don’t want to start vomiting tomorrow even before they start giving me the treatment. – or to be retching in anticipation all the way down the Fulham Palace Road.

According to the experts, because ANV is a learned response, behavioural interventions are especially useful in managing it, using techniques that focus on helping patients relax more before chemotherapy and enhance feelings of control. According to the US National Cancer Institute, what works best is ‘Progressive muscle relaxation with guided imagery, hypnosis and systematic Desensitization.’

Well, that would be nice, and they probably offer something like that at The Haven but as I’m having chemo tomorrow a quicker fix might be useful. Happily, it seems there is one available:


“While antiemetic drugs work well in controlling CINV, they’re not as effective
against ANV once it has developed. The anti-anxiety drug Lorazepam has shown
promise in preventing ANV, however, by stemming memories of vomiting
associated with chemotherapy. Studies show Lorazepam works best when given
the night before and the morning of chemotherapy.”

Right then – that’ll be one Lorazepam tonight, and another one in the morning.

I don’t think the Lorazepam will fix the dread though, because ‘anticipatory nausea’ is only a part of the dread, not the whole: when I think about having more chemo my whole being shudders, body and soul, not just my stomach. The dread consists in knowing what is going to happen to you, and just how horrible it will be, and it creeps up on you as the next dose of chemo approaches, getting bigger and bigger until it blots out the sun.

That’s what dread is, for me: and if Søren Kierkegaard had to undergo a course of chemotherapy, I’m sure he would agree.

The silence of the organs


Day 72 

General status update 


Chemo Demons – all temporarily absent, due to the one-week delay before FEC4. A brief semblance of normality has returned. They’re all off doing God knows what, but will doubtless be back tomorrow to get a good night’s sleep before going back on duty forFEC4

Anxiety level (1-10): Out in the sunshine today, all seemed well with the world, and was; but in 2 days’ time…

State of mind: When I think about going back to the chemo ward on Thursday, my stomach turns over. It is an actual physical sensation, brought on just by visualising the chemo ward, the machines and the tubes, and the plastic bags of chemo drugs. I shudder, internally and externally.




It’s 3.30 pm, and I am walking in the sunshine on the Thames towpath, somewhere between Hammersmith Bridge and Barnes Bridge. It’s an improbably beautiful day, and it feels as if I’ve been let out of prison. Today, for pretty much the first time since I started chemotherapy treatment 70 odd days ago, I feel – well, utterly normal.

The one week delay before my next chemo treatment, Fec4, has meant that the toxins have had time to wash out of my system: there is no nausea, no toxic stomach, no weakness and fatigue. If, as the French surgeon René Leriche wrote : “Health is life lived in the silence of the organs”, then today my body has produced a reasonable facsimile, at least, of health. I’ve got over the virus, and my neutrophils are presumably back in fighting form, because today I felt strong enough to walk down to the river, and then along the towpath for half a mile or so towards Barnes.

It’s a beautiful day – an incandescently beautiful day – with a clear blue sky and sunshine that feels warm on your face. It’s a day that says spring is nearly here, that the natural world is waking up after its long winter sleep, and there is a throng of people relishing its blueness and brightness down by the river: rowers, runners, cyclists, walkers, people pushing buggies or walking their dogs, crowds of people sitting at tables outside the riverside pubs, lovers entwined on a secluded bench. I am more happy than I can say to be amongst them.

Last year, I used to walk along this towpath from Hammersmith to Barnes Bridge and back every day; it’s the one place in this busy part of West London where the space, the light, the trees, the birds and the water allow you to forget that you are in the heart of one of the world’s great cities. Today, I am exhilarated to be out here again: it’s such a long time since I’ve felt this normal, and been able to walk this far. I’m tiring, but instead of turning and heading for home I stop and sit down on a bench for a while, to savour the sunlight, the air and the freedom.

I close my eyes and feel the warmth of the sun on my face, and the touch of a gentle breeze from the river rippling through my hair. One of the techniques said to be useful for dealing with the stress of cancer is mindfulness, living in the moment, and in one sense that is exactly what I am doing now, focusing on the pleasurable sensations evoked by the sun and the breeze.

But living in the moment can only extend so far, today: another part of my consciousness is trying to soak up and retain these sensory pleasures, and the glitter of the light on the water, and the pair of swans I watch making a stately progress down the river. I am trying to imprint all these things on my brain, so that when I’m in the chemo ward again on Thursday, going back into my chemical prison, listening to the clicks and gurgles as the poisons are pumped into my veins, and knowing that the silence of my body is about to end, I will be able to close my eyes and transport myself back to this bench, feel the sun warming my skin, the breeze ruffling my hair, and watch the slow, graceful glide of the swans downstream.
