I had gastric bypass surgery done three years ago and it was the best decision of my life. It gave me hope when I needed it the most. I have been able to loose and maintain my weight lose with a healthy eating regime and exercise plan. I would have never of had the motivation to stick to such a plan if I didn't have the surgery. I also had one of the best doctors around who put me at ease throughout the whole process. She was there to help me ever step of the way, before, during and after my surgery. Dr Marina Kurian is a famous doctor who also did Al Roker's famous gastric bypass surgery. I was lucky enough to have her do mine, which put me more at ease following his story, knowing how well he did with it all. You should check out her website theres some great information on it that I think might help put you at ease as well. http://www.noobesity.com
Good luck with everything and keep the faith.
