Help interpret my sleep study

Posted by bfpsu on June 05, 2008 at 15:16:28:

I am 39 years old, 5ft 10in, I weigh 190, my BMI is 26.5.

Ok, a few years ago I started waking up during the night a few times, this turned into a regular occurence, which also turned into early morning awakenings. Even when I have the chance, I can never sleep to the alarm clock and I always wake frequently through the night. Saw a sleep doctor, had a sleep study and was diagnosed with sleep apnea, 14 AHI. Tried CPAP and hated it. Had a UPPP and lost 10lbs and had my second study which is listed below.

My sleep doctor said, well you are now only 7 AHI, exercise, avoid caffeine, blah, blah. ENT who preformed the UPPP was estatic, 7 AHI, it was a success to him. What has me worried is that I still wake up frequently during the night and I still cannot sleep in at all. If I go to bed at 10pm, i wake up 3 to 4 times but at around 4:30am I start having vivid dreams and wake up every 20 minutes or so until I just get out of bed because I can't sleep anymore. I get out of bed feeling totally unrefreshed and somteimes have muscle pain. I noticed on all my sleep studies, including this one that I don't get any Stage 3 or Stage 4 Sleep. Is all this still the apnea? I'm seeing a sleep dentist in two weeks for an oral appliance.
Any comments/advice, etc. is very much appreciated.
Thanks
