Only get a little bit of sleep every nite. And then when you actually get to lay in bed, you're so tired that all your mind can do is shut down and disappear.
Oh - and it took me only this long to figure it out.
Although it makes for being tired all day too - but at least the dreams don't taunt me.
Perhaps one day I can not be tired all day, but also be able to sleep good at nite. Until then - Hello Mountain Dew!!
