Whenever I try to go to sleep it may take me up to an hour or two to fall asleep. I have tried reading before bed, not watching tv or going on the computer before sleep but nothing I have done (other then using unprescribed drugs, i know i know) seems to work. I just lay in bed going through the events of the day thinking. The act of trying not to think implies that I have to consciously not think which does me no good.
