Now here you might be on to something. I have no set sleep schedule whatsoever. I pretty much just sleep when I get tired , and now that I'm on break, get up whenever I want to. I'll have to look into this one, although it may be difficult to change.

This does take a lot of discipline. My friend has substantially improved his condition by very strictly regulating his caffeine and alcohol intake, and going to bed and getting up at certain times. He's less fun to hang out with since he started doing this. [img]/images/graemlins/smile.gif[/img]

Here's a reasonably good primer:

I do want to reiterate that drugs are very rarely a long-term solution to sleep problems. Yes, Ambien or Nyquil or whatever you get will knock you out when you first start it, but it will lose its efficacy over time. At that point, if you stop taking it, the withdrawal will make your sleep even worse. I suspect the MDs and med students would agree with me here.
