I had open RNY too. Molly and I had a long talk Sat. night and I told her all about it--it was a really scary situation. Mostly because it was at night and I had no one there to advocate for me. If it were not for the iCU nurse I would probably be dead today because my doc (despite being world-renowned) was IMO a doofus. It's so funny to me that so many of us share similar histories and experiences, in one way or another. Maybe that's why we all get along . . . . (to mis-quote Rodney King)
My issue is that there ISN'T anything I can't eat. I wish I was one of those who gets sick eating chocolate and such--but no.

The only time I got sick is two or three months after the surgery I went to breakfast with a friend, had 1/4 waffle with some maple syrup and the maple syrup did me in. Haven't touched it other than sugar-free since. (but I bet I could eat it now). I also never started drinking soda again. Just didn't miss it. (Couldn't wait to get coffee again, however!)
Ex-DBF gained about 40 pounds during the three years we were together because he would eat his meal and then all of my leftovers. (Made me mad a lot of times because I wanted it the next day for lunch!)
