Interested in Lap RNY

Hi Everyone, I scheduled to have LapBand 11/07 and then again on 02/08. Both surgeries had to be cancelled. I am now thinking that maybe bypass is a better fit for me. I'm pretty well versed in the Lap Band pre-op and post-op diets, and what to expect from the Band (I have 2 friends who have had it done) but not aware of how different the preparation for bypass is. Also, is the stoma smaller in RNY? Does vomiting occur if food is not chewed thoroughly? This was the scariest part of having Lap Band, the experimental eating and vomiting as the band gets filled. Any input from you guys would be helpful. PS - If I'm posting in the wrong section, sorry, still trying to navigate this site! Looking for a surgeon on Long Island, Suffolk County (Previous Lap Band surgeon was in NYC - too far for me to travel) Thanks!
