Many of the 'rules' around what is safe to eat for patients undergoing chemo is similar to pregnant women. Also, chemo kills all the good gut bacteria, so diarrhoea, terrible wind and other related gastric issues are pretty much a certainty. The type of chemo OP is having also kills all the rapidly growing cells in her oesophagus, so acid reflux is a certainty. Hopefully lansoprazole has been prescribed.
@4seasons Drink as much water during the infusion itself as possible, and for the rest of the first 48 hours of each chemo cycle. This will help your gut. Also, ask for a better anti-sickness tablet, I found the one of the ones I was given made me unwell, but ondansetron was better. I also refused steroids. This alone made my stomach so much better. Due to this, was also prescribed levomeprmazine which helped me sleep through the worst of the first week's chemo cycle.
Sadly, your husband doesn't really know how to cope with things, but at the same times, not many people really know what to deal with someone else undergoing chemo. Tbh, taking note of your temperature during the first few days of chemo is the most effective thing to do because in all likelihood, you don't need to rush to hospital due to chemo after effects.
I was somewhat lucky inasmuch as I underwent chemo when I was single, living alone and had to take responsibility for myself. I had a much better time keeping myself in check than another friend whose partner was an absolute pig to her during this time. Try to remember, your husband is trying, particularly in terms of cooking for you. Spell out what you can and cannot eat. You really can't expect anyone to know this. I know when I was in a similar position, I was very clear to those who wanted to help me what I was allowed and what I wanted, and what I did not. Ultimately, you need to rest and not be stressed. You have to tell your husband what you need from him at this time. Unfortunately, you can't rely on anyone to know what you want or need.
Wishing you well for the rest of your treatment and recovery.
