Go the fuck to sleep

Here is my current wish: I wish I could program myself to sleep on time.  Ideally, I'd set sleep/wake times - I'd get warnings at 30min and 10 min before sleep time, and I'd get 20 minutes leeway in the morning (though of course this could be reset if needed).  Sleep is entirely difficult.  (I'd rather not have to eat than not have to sleep, but that's only because I have alllllll the food issues.)
