I'm so sorry you are having such down days. But chemo does that to you. I'm not sure what kind you have but I had diffuse large B-cell NHL and I was on some pretty horrid chemo.
My experience was days 1 and 2 weren't too bad. I mostly complained of extreme fatigue. My worse were days 3-5 with the nausea and vomiting. I tried to get calories in me by Boost and Ensure but even that didn't settle right. After like the 6th or 7th day I started to feel a bit better.
And unfortunately this was the pattern after each treatment. Some tolerate it better than others but I wasn't one of the lucky ones.
I hope you're feeling better today and the grumbling goes away.
