I believe that I suffered from apnea for many years before I was diagnosed. I have been sleepy at the steering wheel forever. Finally, when I was having increasing problems including fybromialgia, it was the rheumatologist who sent me to the sleep clinic and sure enough. I had snored my poor husband into the other side of the house and my children and a son-in-law teased me about hearing me from several rooms away. Not long after starting the use of the CPAP we had guests and DH had to bunk in with me and announced that I had passed his sleep test. Over the years the machines have gotten more compact and quieter but still a bit of a pain to haul with me when I travel but I wouldn't dream of not doing so. I also have restless leg which commonly occurs with apnea and take a generic anti seizure drug at night for that. Mirapex works very well but costs the moon.
You need a sleep specialist if you are having problems. It sounds from some of the posts that the docs some of you've seen were not up on the latest developments. A tip I recently learned from my sleep doc which she said she learned from a patient is to use silicone earplugs from the drug store or Walmart to help with leakage from the edge of the mask. I have a very narrow lower face and even with the smallest full face (my mouth drops open)there are leaks sometimes around the lower part. You rub the earplug between your hands to make a crude string or cylinder which will adhere to the soft plastic that fits against your face. No more leak!
Sweet dreams everyone. I have a quilt to make.
