Oh man, I could relate to this, in early 2000 which stemmed from Oct 1999, Either I didn't sleep, or I had gone 8 months only with 2 hours of sleep per day. . . eventually once under treatment for Bipolar-II, I got sleep, but still got and still do, go through periods where I can't sleep, and I understand how that sucks.
Do you find when this happens, that you feel so wrung out the next day? Sometimes (often) I do, but oddly other times I seem to feel like I didn't lose any sleep at all.
I send you wishes of luck with this.
Please take care now,
