I'm what you could call a "severe insomniac", in fact I barely got to close my eyes last night, now I'm tired but if I go to sleep I'll just **** up my sleeping schedule even more.
Question though, why are you so set on trying to find/use really addictive opiates instead of bud? Although they make you feel great right up until you pass out, you really don't want to go down that road. Opiates an alcohol aren't good to use as "sleep aids" because you'll probably just end up becoming addicted to either. As long as you don't have a real speedy sativa, herb has been the most effective for me.
If you must stay over the counter, chill out, relax, and clear your mind. Then take some nyquil, take a nice long warm/hot shower, then jack it. You gotta be strong willed to stay up after that. //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif
