I have been on a two month journey to get a vertical sleeve surgery. Just two weeks to my scheduled surgery date; just to be told the insurance will only pay for RNY. I spent a lot of time researching the sleeve. Now I have to decide in a day or two if I want RNY. Can someone tell me all the drawbacks. (Sweets alcohol etc. ). I don't have a big sweet tooth but do like them once in a while. Also what are the pluses over the sleeve. THANKS.
