I've posted queries about it myself in the past (run a T-Nation search for "CPAP" or sleep apnea)
In my experience, I've had a Resmed S8 for the past few years, even took it on my last vacation out to Cali to visit family. Helped out a lot in terms of keeping me awake, alert, & have a much better time overall.
Prior to that, I had a another Resmed model but to be honest I was not really into wearing it consistently, hence I suffered from daytime rage & exhaustion, headaches, etc.
I am confident my current medical issues are in part due to my not wearing my CPAP more often, so make sure to wear yours, suck it up, & just get used to it...
It will take some time to get used to strapping up like an astronaut/fighter pilot before bedding down, but the benefits of not passing out while stuck in traffic in the morning & not drinking cups of coffee in the afternoon just to get by are worth it.
You also stop having to get up so often to urinate, as sleep apnea F**s with your kidneys to some extent (increases pressure in your kidneys or something along those lines, increasing rate of urine production & need to urinate)

Granted, I need to still get my bodyweight down, the sleep specialist I saw said a lot of Asians have this (I'm Filipino, a high # of us have sleep apnea, in his practice he has seen) & I might still explore the tonsillectomy option.
For now, though, it's the best solution & bottom line, give it a month or so to see the benefits... Your strength will go up & your recovery time will benefit as well (more restful recuperative sleep)
Just a thought; you might just need to be fitted for a better-fitting mask/nosepad setup for comfort maybe?
