It is common to have regrets immediately after surgery. It gets better but not overnight. It took me 6 months to reach my happy state when all the problems seemed to melt away.
The three most important elements after RNY gastric bypass surgery are to meet your daily Protein, Fluid and Vitamin requirements. food is secondary because your body is converting your stored fat into the energy that drives your body. Thus you lose weight.
Weight loss is achieved after surgery through meal volume control. You begin at 2 ounces (1/4 cup) per meal and gradually over the next year and a half increase the volume to 1 cup per meal. With this minuscule amount of food, it is next to impossible to meet your protein daily requirements by food alone, so therefore you need to rely on supplements such as Protein Shakes.
This article describes my experience after surgery. http://www.breadandbutterscience.com/Surgery.pdf
I had gastric bypass in the beginning of August. By mid-October I was able to eat oatmeal and fruit BUT I had to start very slowly. Even now I can't eat much more than a half a cup of anything at any given time. No dumping, but sometimes nausea and discomfort that passes in about a half hour. I started fruit with applesauce and canned peaches and moved on from there. The thing is to try little bits, and then if something doesn't work once, wait a couple of weeks and it might be fine the next time.
