I gained 45+ lbs when I was taking Chemo because of the steroids that I had to take. It took me 18 months to even start being able to cut back. (steroids give you an appetite like a lumberjack) Right after Christmas, I started on Weight Watchers that had been the only plan that ever worked for me and I've lost 23 pounds so far. It's harder sometimes when we go out to eat, but you can do it. Keeping a food journal is a key element in success. Plus lots of water. Good luck. You can do it, just keep on trying.
