I'm glad I read this thread this morning, because I ran out of bupe yesterday, and clinic is closed next two days, and there was nothing in stock at home to get through the jonesing, so I went out to get diazepam or clonazepam from the streets.... street shuffling, one thing led to another, and the best deal available at the time was a quarter gram of brown heroin, so I end up with that, and fuck up when attempt at shooting - when I released the torniquet, the needle was basically swallowed up by skin and it hurt plunging (used accessory cephalic vein on lower arm), and I was really amazed at how fast the blood clotted in the warm solution, so I figured I am not shooting that somewhere else and risking blood clots... and thanks to this thread, the shot didn't go to waste, but up my ass... No rush though, and twenty minutes later, I snorted a small line to supplement. I guess I'm all right now, but I wish the clinic was open, so I could have just gone to pick up more bupe... and then I am also out of sterile filters, so I am either going back to sublingual bupe, or intranasal, or rectal, but the whole game of filtering the tablets and shooting them has taught me A) how to self-administer an IV shot, and B) how one can fuck up one self by self-administering IV shots, so with that in mind, I guess there are plenty safer alternatives, and now I know the basics of IV'ing and should leave it at that. The IV'ing mainly started out of major curiousity, and also as a way of titrating my doses easier, as I am near the end of my ORT at quite low doses and plan to jump to a clean state soon... But apparently I still get jonesey on day one w/out bupe, so maybe I'm not ready for the jump. Either way, the last leg of the taper will tell, and I cannot afford to go back to using heroin as an alternative, and I do not want to. But thanks to this thread, I'm sure the contents of that shot ended up at their desired place... But I was expecting a sort of rush, but I guess it could be remnant bupe blocking, or that I simply didn't plug enough, or that I have expectations beyond the capabilities of heroin up the ass...
