I have been diagnosed with Obstructive Sleep Apnea and have been using a CPAP for a couple of years. I have stopped using the CPAP machine and starting using a mouthpiece instead. It seems to be working for me. I purchased it online from off of the TV ad:
Either way, do the sleep study so you can determine what type of apnea you may have. Obstructive can be helped by surgery, but Central Apnea is a totally different thing. Mental in causation, so the surgery probably wouldn't help much.
