Yeah, sleep is elusive.
Mine is a combination of just general elevated stress due to covid, a sprained ankle, a broken car and washing machine and various other things I can't get fixed right now...usually exercise would help with insomnia but with a sprained ankle I can't really exercise.
I'm on a 6-7 hours per night kick right now. Hoping it settles back down. I just wake up every day between 1:30 and 3AM with a jolt of adrenaline - - aaaaand, I'm up.
