My husband and I both had the surgery within a month of each other. We had one of the best surgeons, a pioneer in the field who retired a couple of years ago.
Our surgery was in 2003. My husband lost 180 pounds and I lost 160 pounds. We neither one had complications and I attribute much of it to Dr. B - he made us take a psychological test (to ferret out any 'cheating' tendencies) and we had a 90 day period between our application/review and surgery, just to make sure we were committed and did the prep work (physical and mental) he recommended.
The best advice I can give anyone who has this surgery is to FOLLOW THE RULES. Everyone I know who has had complications didn't - they continued to smoke, drink carbonated drinks during the 6 month healing period, didn't take vitamins, didn't walk and do light exercise, drank alcohol, lifted too much weight too early, etc. Dr B also offered support groups and fashion shows for patients so we could regularly share and relate with others who had the surgery. It has been 8 years and I am so happy we did this.
