GRB5111 - lucky you! I lost 216 lbs. (before failing maintenance) and still had my sleep apnea. But fortunately, I also had an awesome sleep study center tech and pulmonologist who helped me find a non-torturous mask that I came to like, which allowed me to sleep on my side, as I prefer. For me, I will always have sleep apnea...I did kick my high bp of about 30 years though with diet change and weight loss...that was a great thing
