I used to be on a schedule of sleeping 8 hours a night, but lately, it has been a total mess. I will stay up between 24 and 48 hours, then sleep for almost 20 hours. I think I need to contact my Pdoc and see if I cannot fix the situation. Before medication I would stay up for four days straight; the trippiest thing one can do without being high. You see, feel, smell, hear things that otherwise a healthy individual would not. i remember the artworks that would come from being sleep deprived were strange and distorted. What I thought was a masterpiece turned out to be warped.

Sorry that you have trouble resting. You can always talk about it, though.
I have known people that took heavy tranquilizers just so they could sleep about 5 hours at a time. One guy even would be awake for a whole week and I would constantly keep a check on him because he would sometimes pass out for a few minutes, resulting in a fall. People have their problems, and sleep is a big one.
