I am having surgery on the 16th as well and we decided the RNY because I have acid reflux issues a lot. Apparently if you have GERD or problems like that the sleeve can possibly make you still suffer from that alot. I was told both surgeries give the same result at the 3 yr mark but the sleeve is more gradual which will help with less loose skin issues.
I have a few friends that have had surgery and also told me to make sure I have Gas X strips and antacid chews on hand before surgery already. Good luck!!
