I started my pre op last week and have failed miserably, I've tried to tighten up and do better yesterday and today, but I am so hungry. I have protien "supplements", shakes, bars, Soups, that the doctor office makes and sells. I think it's a little shady that we have to use the products that they manufacture. Hopefully I can pull it off next week, this is depressing me, I didn't think I would have this much of a problem. Dr has only refused surgery out of several thousand, and it was a RNY I believe where they found undigested food in colon. I have major PMS also, which is making it harder. I admire those that can do it without cheating.
