What all were you taking/are you taking for vites and protein? I have a quite radical RNY, and I know lots of ppl who didn't follow the program we were given and went to our local U to have their surgeries back down. Not reverse, as you said, but taken down to a lesser surgery much as you did.
The result for most was still having deficiencies and substantial regain.
I'm sorry you had such a bad experience. They always tell our ppl that "too much was bypassed" when the problem was really that "too much stubborn between the ears" since we had good launch instructions, especially for the 90's! They had the same starter instructions I did, and they only got better over time.
In your case, you probably did not have a good launch and that is so, so sad. My dh is 6'1" and his ideal is 175 or so, his low on the way down was 162 and he now holds about 180, depending on how many cookies leap into his face.
We pretty much had the maximum bypassed. I'm more so than he is.
Now, while you were told that your transected stomach cannot be connected, I've sent 2 ppl to CA to have their RNY's changed into DS. That involved rebuilding their stomachs completely and it was done! Both had serious complications from their badly done RNY's. Both are doing very well now. Not many docs will take that one on, though.
