i have had trouble with sleeping for a long time now, I am always tired and wake up all through the night like I aint breathing but I seem ok, I had a couple sleep studies over the years and one said I had sleep apnea and I was put on a cpap machine but 2 others after that say I don't have it, I have fibro and a few other dx that they are saying is causing all my symptoms but I just cant shake thinking the apnea is still present, I know I snore a lot and I toss and turn from pain in my body what else can I try
