When I was preparing for surgery I spent 100's of hours researching the different surgeries and used this forum to help support my choice and decision.
I will be 3 years out from Sleeve surgery in September and these past 3 years have been the best ones of my adult life. I'm not crazy thin and at my current weight I am literally still considered over weight according to the BMI charts, but I'm happy and healthy. I take my vitamins everyday but really even without surgery you should be doing that. I actually have always had some vitamin deficiencies so surgery didn't change that. I am able to walk forever and even r 5 km now and I wasn't able to do that since childhood.
My personal opinion is only based on what I know but the lap band has very low success rates and most people will lose in the beginning but have regain which leads to having the band removed and than revising to another surgery either by pass or sleeve.I think it's a was of time and energy to have it done and than put yourself at risk later with 2 more surgery to accomplish what you set out to do, it's unnecessary surgery when you have great choices like sleeve or by pass.
good luck with your research and I hope you are able to see the light at the end of the tunnel and choose a surgery that will suit your lifestyle. It's probably one of the biggest decisions you'll ever make next to marring your hubby of course :)
