I am 12 years out from the MGB and I am totally happy with the results. This is an extremely powerful surgery and it is very difficult to sabatoge. In fact, I got too thin initially. Yes, if I was a total couch potato and always picked mega carbs to eat, I would gain a little weight but why would I do that? Why would I have my body altered so much just to not take advantage of the tool. I know of only a hand full of folks who did not lose weight. and had revisions.
I drink lots of water. I use moderate salt for hydration and I try to pick good food choices. However, being able to eat anything I want at this point, a little self talk is needed sometimes. I don't crave like I used to. Quantity is still very small. I made an excellent choice.
