Here's an idea... move your fucking electronics out of your bedroom! I know some situations don't allow for this, but I think your bedroom should be for 2 reasons: sleeping and fucking. If you use it for more than that is screws up your perception of sleeping and your mind can wander to other places when you're trying to sleep. I know I had my computer in my room for several years and I have to say I think I sleep better without the added noise and lights and shit.
