First of all, welcome to the board. This is the place I discovered a few weeks before my surgery and it helped me so much. I was nervous and didn't know where to turn and I found lots of support and great answers here.
If you want this surgery, you're going to do great. I've been feeling great and losing weight since my surgery on May 21st. I already feel like this was one of the best decisions I've made in years. I asked tons of questions and felt well armed for the surgery, there are lists on here for things to get in your house before the surgery (great help), look at the pre-op question section for ideas.
Now, ask your questions and good luck
