I did a sleep study last year after months of especially terrible sleep (getting up to use the bathroom two or three times, waking gasping for air, head pounding). I was so tired all the time, I could hardly function.
The sleep study was an in-home study. They sent me the kit in the mail with instructions and I hooked myself up to the machine and went to sleep, thinking I'd never get any rest with all the crap stuck to me. And I slept better than I have in about five years.
So of course the results showed I had no problems. My doctor dismissed the issue, since the sleep study said I was okay (which I'm still angry about). I'm moody, emotional, short tempered, can't concentrate, and suffer from chronic headaches.
But the test says I'm okay so that's all that matters.
I've gone back to the doctor several times since and she's worked to alleviate the stress she feels is causing my inability to sleep but so far, nothing has helped. I don't want a c-pap either, but I'd like my life back. I haven't functioned normally in years.
