Envexed... I can not give you advice regarding the machines & masks, since fortunately I do not suffer from Obstructive Sleep Apnea.. but I can tell you how important, for your long term health, dealing successfully with OSA is. Hopefully you will be able to find a good, comfortable mask for yourself, and you can begin regaining you REM sleep.

There are also surgical procedures that may help or even fix OSA, but none are 100% guaranteed.. Uvulopalatopharyngoplasty (UPPP) removes the uvula, the immediate palatal soft tissue and the tonsils, resulting in (eventually) a tauter upper palate and a more open airway. Recovery is generally quite uncomfotable... but if it is successful (~50/50), those two weeks are well worth it. Another is Septoplasty for deviated septum.. obstructing one's nasal air passage.. often stemming from a previous/old nasal fracture.

Hopefully your results comeback as mild OSA and you can find a good fitting, quite mask (they have improved alot in the last few yrs).. but if moderate, and especially if severe, you need to find a solution to overcome it and make sure you oxygenate youself at night. OSA resultant snoring/gasping obviously sucks for spouses also.. but the potential hypoxia can and will eventually lead to Cardio problems including MI... it is not good to starve to heart of oxygen night after night after night.......

Propper fitting CPAP mask will basically eliminate OSA... restoring REM sleep and assure oxygention of the heart at night.

Good luck to you

--also.. FYI.. kids with Tonsillaradenoidalhypertrophy: big tonsills and adenoids... can also suffer from certain degrees of OSA.. greatly reducing their REM sleep. This in turn can affect their daytime awake/awardness -> daytime somnolence.. and can affect their retention of info during school and therefore, IMO, grades.
