I am awaken at 4:00 a.m. out of a dead sleep from pain from head to toe - literally I know depressed bipolar and this just doesn't seem to fit. No tears, no crushing chest pain like your last friend died, can have manic moments that are not out of control. No laying in bed unable to move or will to live or feelings of depression or despair. Most times, I feel pretty good emotionally. I have a light for SAD
little to much stimulus, don't believe in l-carnitine, tried that for a while, am on HRT, according to gyn that takes care of the vitamin D needs plus the milk in the morning. Not familiar with amino acids
For sleep study first doctor was an M.D. nothing physical was interrupting my sleep. Second doctor was a Ph.D. bozo that ripped me off with all his computer gadgets and when I told him to hit the road, he suggested I try melatonin that worked for a while. I even take Requip for restless legs. In answer to your question about sleep study confirming disorder or not, that would be a no on anything.
I have more than just a throbbing headache. I get headaches that include my whole head, neck and shoulders, head and jaw and the javelin through the temples.
I occasionally have jaw pain or my teeth hurt.
