I had the gastric sleeve (not bypass) and am so happy I did! Don't get me wrong! The first 2 weeks after the surgery I thought I was going to die! Lol once my body adjusted to being off sugar, caffeine, and I knew I wasn't going to starve to death, I was fine.
It has been almost 2 1/2 years and I have lost and kept off 130 lbs. I still have to watch what I eat, exercise, and maintain a healthy lifestyle to keep it off of course. If I had to do it recommend a surgery, I recommend the sleeve. It is not as invasive as the bypass and you still lose 80-90% of your excess weight. With the lap band the average is only 40% of your excess weight is lost. Hope this helps give you some insight and that you do what is right for you. God bless!
