Hi Karen!
My advice to you is to do your research if you haven't already. There are a lot of different kinds of weight loss surgery and a lot of different complications each can have. Make sure you know what the risks are, know what potential problems you can have, and make sure that you're comfortable with the decision. Read the boards here and find blogs of people who have had the surgery!
The whole process went by really quickly for me. I went to a seminar, had an actual appointment at the office two days later, and scheduled the surgery at that appointment for four weeks after that! I was a little dazed through the whole thing, really. I'd researched for a few years and then when I finally made a move it was seemingly lightning fast.
Best of luck to you!!
