Rosie, firstly, I'm very sorry to hear your husband is unwell. I had chemotherapy last year, so I'll try and remember a few tips for you.
1.Hospital will give you tips on avoiding infection, generally my DH was just a bit more vigilant than usual with the cleaning, esp. in the kitchen, and used my own towels etc. Just as a precaution. Any signs of infection, temperature etc. contact hospital straight away.
2 Don't be afraid to make full use of your chemo unit/ cancer unit at the hospital. Any worries about Side effects or anything get in touch with them.
3 They'll give you dietary info. But basically he may feel sick, weak, not hungry. So little bits of what he does fancy, plenty of drinks, try to increase the calories in the food he does eat (things like full fat milk, butter in potato etc.)
He will get to know what things he can eat - the main problem is you get a strange taste in your mouth with chemo - sometimes stronger tasting things, or citrus tastes can be nice.
4 He'll discover how the chemo effects him (it varies from person to person and with different types) so he be able to predict his 'good' days, and when he's going to feel a bit wiped out.
When I was really exhausted - I just went to bed, and listened to audiobooks.
5 skin can get quite dry and rather 'soft' , so a nice moisturiser, and use baby products in the bath and baby shampoo for head.
I also used a baby's toothbrush and childrens toothpaste - they are more gentle on your gums and you often get a sore mouth.
I have to go out for a bit, - and I may well have forgotten some things, but will return to thread later.
And yes I'm sure a cancer thread, or a cancer carers thread would be a good idea - lots of people on here unfortunately affected by this bugger of an illness. Best wishes to you and DH
