I have sleep apnea. Now whether it's connected to my A/P and depression I don't know. However, I do know that it is connected to my weight. I weigh about 50lbs more than I should and could stand to lose 70lbs to be even better. The more you weigh has a direct effect on how well you breathe during the day too. It's hard on your body. So, I'm not doing myself any favors. I also had a deviated septum that was repaired in 2005 I think and that has made a difference too. I now breathe better because of the surgery.
I know I really didn't answer your question. But if you feel that there is a problem, see you PCP and have him direct you to people who do sleep studies. I had to spend a total of three nights (not consecutively) at a sleep clinic attached to wires, tubes and the mask over my face. Now that I have the machine, I love it. I notice a huge difference when I sleep without it. I'm more fatigued, have less energy and am just down right tired without it.
I would do this sooner than later because it is a SERIOUS problem. Not to add more panic/anxiety for you or to scare you but people can die from sleep apnea. It literally means "no breath" "no air", you actually stop breathing for a time. Please, please get checked.
I really slept better than I thought I would. The place I went had double wide beds, you could bring whatever you wanted from home, blankets, pillows, jammies, anything familiar. It was kinda weird being hooked up to everything but it wasn't a bad experience. They expect you to only sleep 5-6 hrs anyway. By then they usually have all the info they need for that particular test. Then they have you go back another time to see what settings you need to be on and adjust things.
It wasn't as bad as it sounds, even with my A/P, I survived.
anxiety and sleep apnea are 2 different things but I have both, I did my sleep studies with a big dose of valium which I didnt tell them about and got enough sleep, they only need a few hourI now use a CPAP machine and have much more energy but its not an anxiety cure
I would do the study, but an alternative sometimes is they lend you the equipment and its done at your home
there is much undiagnosed sleep apnea, there are several types, most involve heavy loud snoring, sometimes there are pauses with no breathing but not always
the main complaint is exhaustion or cronic fatigue, its often misdiagnosed as depression
videocameras that work in low light are useful, get someone to tape you when its bad, you can show docs the tape as evidence
