The side effects which I notice are headaches and slight nausea, but these can be minimised by drinking lots of water. Going off to the bathroom while attached to a pump on a wheeled stand is a nuisance, so it is tempting not to drink so much, but you have to treat it like a job: processing H2O!
The other challenge is distracting yourself for long periods of time with limited resources. You can read, listen to music, do word puzzles. There is no wifi connection here, or radio or reliable mobile phone reception. We are seated in close proximity to one another, so there are strangers on either side of me. No conversations are private. From time to time you get to know a fellow patient a bit better, and it is a real bonus to lose yourselves in a chat for an hour or more. Sometimes, frankly, I don't want to talk, it is too much effort. Why am I tired? The underlying condition, the effort of leaving work for my school classes, the problems of getting ready for a day on a public ward when you cannot use both arms/hands to wash, dress or do your make up.
There is an alternative way to have this treatment. Instead of coming in for a week every four months, I could come in for a day per month. I'm nervous about changing the regime I'm used to, and prefer not to be reminded more frequently that I have C I D P. I should probably review my attitude towards it. Pretending to be normal, ostrich-style isn't so intelligent, is it?
