nugs this isn't the best advise and i'll admit it but i work fucked up hours all the time and so my "sleep cycle" is vitually nonexisistant. and i am used to having to stay awake so i get used to being extremely overtired and i try to sleep and i can't cause i feel like i will oversleep or i'll sleep and get up like every half hour but when i REALLy need sleep and can't fall asleep i take 2 muscle relaxers(prescription). knocks me out and i stay out until the alarm goes off. if you don't have a script for them though you gotta find someone who has them. just can't do it all the time or you won't be able to fall asleep without them.
