Wow, it's nice to know that I am not alone. I am almost 3 weeks post op bypass and I am really regretting this. It's not about missing or mourning food, I just don't feel right. I had a very difficult time with whey protein, but I'd rather put up with the discomfort than try to palate the soy (I could not even swallow the soy- It was disgusting). But I am tired, depressed and just have no motivation to do anything. I don't know when I'm hungry or full, but I just feel lousy after a few hours. I know this has to get better, it's been a rough start.
