Dear Lisa,
I can't speak for you but I can tell you what my friends have said who have had by pass surgery. Not one of them is sorry that they had it done and all have said they would do it again in a heartbeat,(maybe not the day after surgery, but very soon). Most of them have had life long battles with weight control and this has worked for them. I chose a lapband and it has solved my problem although the weight loss is much slower. Even the few who had complications have said they would do it again. If you have had that life long problem and you want to get healthy you might say that this is what you want to do. It is normal to have doubts the day before surgery. Wishing you the very best.
