INSOMNIA: a blessing or a curse?

Haven't been sleepin' well in the evening time lately. Went to bed at 4am this mornin' and had to get up by 8am. The night before I went to bed at 3 am. I can't remember the last time I went to bed before 1am. I know I need the sleep, but for some reason or another I find myself always fighting sleep. I got some kind of psychological issue with it. I love to sleep, but whenever I do I wake up somewhat pissed and frustrated because I just wasted a few hours of my life doing nothing. Also I find that in those hours of sleeplessness that's when I get the best ideas for scripts and films and etc. So for now my motto is: "I'll sleep when I'm dead"
