When you can't sleep...

What do you do when you can't sleep? Got any good tricks for me? I read until my brain stops working. Sometimes that doesn't work. Then I write, relax muscles in order along my body, drink Sleepy Time tea, soak in a bath. The last couple of nights nothing seems to be working, so I tried something new. I visualised an old memory, drew myself into it, analysed thoughts, feelings, tried to get inside the scene as if I was writing it... and you know what? I fell asleep! Yep, in the middle of making out in a spa... I slept. Hope I didn't drown!!
