Almost three years ago I consulted a surgeon in my area regarding this procedure. He told me that based on my age and lifestyle, he felt I would see immediate success but then down the road after only a short while I would regain my weight. I was 330 lbs when he and I had that conversation. I had the surgery and the band was put in. In the first few weeks I had a dramatic drop in weight being limited to liquid and blended foods etc while I healed. Taking advantage of the situation I started to get back in the gym. (Which I had a habit of from my youth, was VERY fit once).
Needless to say I am now 220 lbs, at 6 feet (Yes I am a guy), I play soccer again weekly in a competitive league and work out 5 days a week. I have been steady at this weight over a year now. I have never had a fill.
The band, for me, was a psychological device. It gave me a sense of urgency to take control of my self and not to rely on a piece of plastic. I keep the band as a reminder, as a "string around my finger" and ultimately if I ever do slip I will get that first fill and use it as a safeguard.
My point is, believe in yourself and take control of your body and mind. It was not easy for me by any means. I suffered depression, I was a drinker etc etc etc...
Take control, leap with both feet and without fear. You will feel great when your body is healthy and you will reap the rewards of that new life.
