Re: sleep apnea?
A friend of mine had the surgery: removed tonsils and part of the roof of his mouth to open the airway. He said basically it was remarkable the difference it made. With apnea it is difficult to get into deeper levels of sleep/REM... which are critical to restoring the body on a daily basis. He elected the surgery over the machine as he didn't want to mess with a mask every night. Check your insurance, as many plans such as mine do not cover sleep disorders unless it's perceived as medically necessary; I would think potential apnea would be considered medically necessary.
