Missy,
Congratulations! You should be very very proud of yourself, not only for so successfully following your doctor's and nutritionist's directions prior to surgery but for wanting to improve your health and to be there for your children for years to come. I am very happy with my decision to have gastric bypass 15 months ago, and I would do it all over in a heartbeat!
I wish you the best when you go through the surgery, and for a quick recovery and success in the years to come. Feel free to PM me if you have any questions about the surgery or life after the surgery.
Best to you!
