I'm not a doctor. I really struggled in week three of my IV chemo treatments. Loss of appetite, nausea, diarrhea. Chicken bone broth was about all I could stomach. I told my Oncologist what was going on and she adjusted the strength of my chemo meds 15%. It made things more manageable. That change made the nausea go away and my appetite came back and I started gaining weight. Good luck and I hope your situation improves!
