I didn't experience any difference in taste. I often brought a lunch with me and would eat during the 3 hour chemotherapy. I should add that my oncologist wanted to give me a steroid at the beginning of each session. I declined this because most steroids are detrimental to the immune system and I didn't see any benefit in taking it.
I believe it helped that I have been taking vitamin supplement a long time and also eating many fruits and vegetables. For me the biggest downside to chemotherapy was the negative effect on blood counts. It helps to take Papaya enzyme and vitamin b 12 as well.

Another thing suggested by studies is that because use of curcumin, the dose of chemotherapy might be reduced while still getting the same result. Less poison(chemotherapy) means your body may stay healthier. I don't know if this has been tried yet. The standard procedure is give the patient the strongest dose they can stand and still stay alive.
