@glife, there are a range of symptoms and not anyone has even all. Sleep disorders are a big one. I know they found that for years I wasn’t staying in REM sleep. I could sleep 2 or 12 hours and still be tired. I was prescribed small dose muscle relaxant but that scares me now as I now am a recovering addict. My mood stabilizer (carbamazepine) for my Bipolar II seems to help and I sometimes use melatonin to help me relax before bed.
Try to keep a journal, nothing fancy, of symptoms you think may or may not be related. There is a TON of info online now. Just make sure it’s from a reputable site like Mayo or some other (actual) medical site.
