Heroin for me too. I actually have a decent amount but it is far from me (Thank G-D really)...and morphine which is what I have been maintaining my addiction with since this past August.
I am currently dropping on morphine, from a high of 3000 mgs. orally, to now just over 400 orally (only one dosage per day). not only am I yearning for a higher dosage, but I have been beating my body up since August, dosing one time a day.
Duration wise it is good for 8 hours although clinically speaking 4 hours is the listed duration. Ergo, every day, a few hours after dosing, I suffer badly.
I have a huge amount of heroin, an incredible amount of morphine, and an even more incredible amount of Demerol ampoules but need to dry out for a trip to the mainland. Flying into Thailand and even though my morphine and Demerol are Scripted, they prohibit all importation even for licit usage.
I hope to be down to 0 by Western New Year, and then jump back on the wagon with my 10 tonne gorilla in Cambodia...Ahhh...
