I have had 2 sessions of chemo, for stomach cancer, the first 9 weeks prior to major surgery I felt fine and ate very well. After recovering from the op, I had another 9 weeks of the same chemo. I was absolutely floored, slept all the time, I could hardly get out of bed to get to the toilet, had no appetite and I had constant diarrhea. I had to eat with every chemo tablet so ate small meals of yoghurt. Once I finished the tablets I recovered quite quickly. Stick with it if you can Sunneysideup. It'll be worth it in the long run. Wishing you all the best.
