I experience hypersomnia when not in a manic/hypomanic period. This is likely related to Obstructive Sleep Apnea. My sleep doctor, after consultation with my psychiatrist prescribed Provigil. I started taking it about a month ago following a deep depression. I thought that I was at my baseline. But after taking this I felt like my depression truly lifted. I worried I was going to be sent into a hypomanic/manic episode. There are times that I appear to be a little hypo but manageable. Anyone else have experience with this med?
