I began having trouble sleeping when I was a kid, and it's stayed with me off and on my entire life. I never really looked at it as a big deal, but when I was married it used to concern my wife quite a bit. It's been a part of who I am for so long now that I don't remember what it was like to sleep 'normally'.
Generally speaking, if I get three hours of sleep a day/night I'm doing well, and there are many instances where I'll stay up for two or three days or more at a stretch without even trying to go to sleep. I don't mean it to sound like I'm running at full speed all during those times because that's not the case. Because of my health problems I'm unable to keep the pace I once did, and sometimes I need to lay (lie?) down to rest my body, but I don't sleep. It's more like I'm at half-speed and I just keep going until sleep comes.
Too much on my mind, too many books to read, too much music to play or listen to, and too many worries. To me, that's the biggest negative about my not being able to sleep; it gives me that much more time to worry about things. I know it does no good whatsoever, and I also know that it isn't healthy. It's a vicious circle, but I've never found a way to change it.
