If this is what you want..... then I wish you all the best and you deserve to feel good about your choice.
I want to add that I have 2 friends (not close friends) who had this surgery.
Both have continued to struggle with their weight.
From what I've figured out.... you need to address your thoughts and change the way you deal with stress, along with commit to healthy eating patterns and excercise.
Neither of my friends did this, they kept their same food choices and still overate, which made me uncomfortable for a couple reasons. One, I knew they felt guilty about it. Two, we both knew they were defeating the purpose of the surgery. There was even more guilt about food, after the surgery. I don't think that helped them at all.
Oh my.... I must sound like an old finger pointing school marm but.... I really want you to get what you want from this surgery, if you go through with it.
The surgery alone, without changing habits and addressing underlying causes, didn't work.
I'd think of this as a big ol jump start to obtaining a goal. I wouldn't think of it as the solution, kwim?
What becomes habit becomes pleasure. Good luck: )
