Sleep apnea is a serious problem causes all kinda issues...get checked...especially if you wake up from time to time gasping for air like your drowning at bottom of the pool lol...mostly from weight gain the flap in your throat relaxes as you're sleeping and blocks your breathing...sometimes genetic i know couple skinny guys that have it...ive been sleeping with the mask for two years or so...and now i cant sleep without it period lol...i opted for the nose only couldnt do the full face...
