This must be challenging, I’m sorry your father is going through this. I’m on my second round of chemo for stage 3 rectal cancer. The doctors have a lot of anti-nausea meds they can provide. Each chemo regime provides different side effects and severity of the side effects. For me, I try to keep food in my belly which has seemed to reduce the nausea. Bread/carbs have been the easiest to keep down. I don’t like taking the nausea meds (I have 3 types) and I haven’t used one of them but they can help.

Managing chemo side effects is a constant battle and the exhaustion is awful. I wish you and your father all the strength, love, and support you’ll need to get through this battle.
