This exact same thing happened to me. I had my doctor order me a sleep study test for sleep apnea. Sleep apnea is listed as one of the morbid conditions. I knew that I snore and was told that I sometimes stop breathing at night.So, this was basically my last hope or gain 10lbs. Well, it turned out that I had sleep apnea. Now, the ball is roll in my favor. So, don't give up
