I too was a healthy fat person who was not sleeping and thus became borderline diabetic. I got tired of the c-pap machine because it was not helping me to sleep. I had a gym membership and used it as regularly as possible but I was still carrying a big belly, weighing 219 lbs. I am vehemently opposed to any form of medication except where absolutely necessary. I therefore decided to do the gastric sleeve surgery on 3/11/14. I am now 192 lbs according to my Dr's scale and 182 lbs by my scale. The weight is moving slowly but I think it is better than previously. I can live with slow. To fellow sleevers, DO NOT GIVE UP! The alternative is not good.
