So glad you are doing so well. I know what you mean about the protein shakes....they really did lose their appeal after surgery. I don't get sick at all, but do find if I eat too much, or too fast, I feel tired...it seems to go away pretty fast though. I eat chili, scrambled egg, canned veggies, cottage cheese, soups, puddings, popsicles, and that's about it. lol. Actually, I feel fortunate to be able to eat these things w/no problems. Had no problems at Thanksgiving either...just blended the turkey w/a bit of gravy and ate the mashed potato and green bean casserole...yummy...only a few bites of course. It's such a hard thing to give advice on..because everyone is different. What agrees with me, won't with you...and what some like, others don't. I'd say just keep trying new things and see how you do. I've had to toss out quite a few things. I hate wasting food, but sometimes you just have to until you find what agrees with your little pouch!! Good luck!
p.s. you did drop a lot of weight, but I don't think it's too fast. Depends on where you started. I dropped 25 the first month..but wasn't exercising at all, because I was in the hospital for that whole month...so considering you are so active, I'd say you're right on!
