I'm bipolar and this is a regular issue for me. Stress, manic mode, geting into a book or researching something and before I know it, I'll only get a few yours of sleep. I'll lost track of time or just can't sleep from something going on in my life. I wont be tired and I'll usually use my hour lunch to sleep in my car. This can go on up to a few weeks before I start getting back to 7 or 6 hours of sleep. 2 or 3 hours starts to affect me after awhile.

I'll listen to rain and thunder or classical music through alexa and that helps calm me down. But honestly it just has to run its course.

Hang in there, all last week I was only getting maybe 3 hours a night. I'm back to my regular sleep mode. I had to work on a few things to get out of that mode.
