Im 22 and about to start my third cycle (5th treatment) of ABVD. At first I had really severe nausea and could barely eat, and lost about 5 lbs in the first week after a treatment, only to be gained back the second week, no matter what I did. Now I still get nausea after treatment but not really in a way that affects my appetite. My problem now is that my weight keeps creeping up. It was already too high before I had cancer, and when I realized I would have to be home most of the time for about 6 months, I figured if I was feeling well enough I would take this time to lose some weight. I have tried weight watchers and mcdougalls plan, both of which I have had success with in the past (although never reached my goal) but still I gain. Its been depressing enough stuck at home and watching my hair fall out, and now Im getting fatter on top of it. My weight was already what I would consider the biggest struggle and cause of distress in my life, and now its just getting worse. I have read a few posts about other people who have gained weight after treatment was over, but I think they all had radiation as well, which I do not plan to have. Has anyone else had a similar experience, or know why this is happening? Besides it making me feel worse mentally, Im not looking forward to seeing my friends at the end of all this weighing more than ever. And, if there is nothing I can do, Im abandoning this dieting and getting donuts.
