MetroWest Medical (Natick - off Union Ave) - I was refered to there by my physican. I had sinus surgury couple of yrs back to help correct the apnia - it didn't do me any good IMHO. Next step is cutting away the excess tissue around my tonsils, BUT I heard that the tissue CAN grow back.

The sinus surgury had me flat out for 1 week and when I tried to go back to work (Spring time allergies kicked in) and got house bound again for another week.
I have a CPAP machine - used it for 3 months and HATED it - I can use it if I sleep alone. When you break the seal the air hisses out and would wake up my wife. I sleep on my stomach so that makes things difficult.
Snoring loudly and a lot IS a sign of apnia. My wife tells me I stop breathing for long periods of time and she nudges me so I wake up - so far my body wakes itself up.
I feel tired a lot of times. When I am tired I go take a nap, or go to bed. If you are very overweight (get winded walking stairs or to the mailbox) if the apnia doesn't get you then diabetes WILL.

I need to drop some weight as well. Last time I went to a talk about sleep apnia - one guy excercised and dieted a lot and found that helped a lot w/ his SA. He didn't have to use his CPAP machine any more !
If you have more questions you should talk to your physician about it and they can route you to a specialist.
