It's so weird that the simplest of biological functions, just falling asleep, is so often one of the most difficult. I guess there's not always an impetus to sleep, a push, it's not something we're necessarily driven to do (unless you're super tired, which apparently I am not.) Lay still and wait. And wait. And wait some more. Then get up, post to OffTopic, have a smoke, then try again. I envy people who can just fall asleep, take naps, stuff like that, I never got the hang of it. (Also don't smoke, it's bad for you.)
