Hi PricklyPear we are so happy to have you here!
Something that you need to understand about obesity surgery in general, is that it is not a permanent fix. You are going to have to change your eating habits anyway down the road or else you will risk putting the weight back on. Something I always ask people, is that if they cannot change their eating habits now before they do the surgery, what will stop them from returning to their old ways down the road thus nullifying the surgery they had?
Look at Carney Wilson for example, she had gastric bypass, lost a ton of weight, and then put a lot of it back on again because she could not control her eating habits. Obesity Discussion made a post about it, where years after her obesity surgery her weight ballooned up to 188lbs.
Carney Wilson from "Wilson Phillips" had obesity surgery but gained back weight
