Damn it, Doc, you've been hit again with the curse of the night dwellers. I don't know how often you get hit by insomnia, but it gets me a few times per month at a minimum. If I have something that I would like to be focusing on (music!) then it's a real gift. If I am uninspired and can't sleep then I get really pissed.
Luckily, a Xanax or two knocks me down effectively. If it's a real bad ass case of insomina though, I just stay up and suffer the next day. As long as I stretch my body out and lay down for a few hours my back and legs can function the next day. The only thing that can wake me up on a day like that is 2 ephedrine, 2 aspirin, and a cup of coffee (The ECA stack, an old bodybuilder's diet trick). That will wake your ass up, guaranteed!
P.S. You might want to ask your doctor about "Provigil" as it is a drug for people with sleep shift disorder (airline staff, doctors, etc.) They have a free 7 day trial if I am not mistaken.
