Farscape, I understand, I know your situation, I was there. You'll be OK. If you feel you're at the end of the rope, then you gotta do something. I don't beleive you'll have any problems with the sugery at all - it's about as minimally invasive as it gets for abd sugery.
I, for one, am pullin for you since I am GB Minus too. Can you do me a huge favor and write back on this forum after you get through w/ the surgery so we can learn about how did. It's very important for everyone to know and to hear about your experience.
The other thing is I really think it's important, post-surgery, not to fall back into bad eating habits. You really need to reevaluate what diet will work. I hope you can get to the point that I'm at in realizing that most American food is poison - full of carbs, trans fats and perservatives. It Gums Up the Plumbing!!! I could rag on and on about diet changes but I'll save it until you get back on the forum after the surgery. OK?
