Insomnia

I've been having a really bad time sleeping. I'm never good, ever since I was a kid, but sometimes it gets worse. It's partially my own fault, as I got myself into a really late rhythm while finishing the novel draft, but that was already a while ago and I'm only getting worse. Lat night I went to bed at 4 am, which is by not means early but not super late for me. I lay in bed, not sleeping, till 8 am. Lucky I didn't have to be anywhere and could just sleep till the afternoon but it's so much wasted time and so tiering to just lay there and wait for sleep. And getting up after the sun has set again, missing daylight completely only makes it worse... :/
