Hi! I had lapband 17 months ago and I went from over 150 units of insulin a day down to 25 units, I would say that was pretty significant. It took a while (probably a year) of weight loss to get me down to only the 25 units. I'm working on getting rid of those 25 and only being on oral meds. Hopefully I will eventually get off those as well. I also have sleep apnea and that has gotten better as well. Good luck, it will happen. Don't get discouraged, I didn't lose as quickly as some people but it has taught me portion control, I never take more than I know I can eat. The restriction won't allow you to over eat as you will throw it up. Believe me, everyone has tried.
