-Take as many warm bathes as you can w/o turning into a human rasin
-Immodiam AD (an opioid that does not cross the BB, but will help your stomach/bowels immensely)
-I forget the name of it, but there is another OTC med that will allow the Loperamine (the drug in Immodium AD) to cross the BB and bind to your receptors. Quinine is one of them, but there's not enough in the Tonic Water they sell in the US.
-Depending on the source you could get a couple lbs of poppy seeds (I know you used to be able to buy them by the bulk at your local brothel, avoid the ones in those small grocery store spice containers they have been washed). Then you make a sort of tea out of almost boiling water, dash of lemon juice, and of course the poppy seeds. Shake for 5 minutes every 15. It sucks, but the longer you shake the stronger it is (IMO), I'm sure there's a ceiling on it though, as the seeds may begin to reabsorb the morphine/codeine/thebaine/whaterver. I dont know. I tested positive for Morphine having done no other opiates in weeks. I was smoking a gram of H a day at that time, and a big bowl of poppySEED tea made me feel high for an hour or so and well for 6-7.
-Lay out in the Sun
-Wank it.
I apologize to the Mods for sourcing... I'll be more careful (I had interpreted sourcing as informing people where/how and from whom to buy drugs illegally).
