ok well i iv'd 4mg and i can say i definitely felt it. the only reason i did it is cause there was no talc in it (which is the most important reason pills are bad to iv). it was pretty nice honestly. i haven't done opiates in a few days too so i guess my tolerance was low, but i definitely have a nice long lasting opiate high. only a couple complications... first is the injection site became swollen. i thought i missed the shot but it didn't bubble or anything and someone experienced said it wasn't a missed shot. its several hours later and its still pretty swollen. can anyone say anything about this? and something else : at some point i was no longer able to swallow solids. i had no problem with liquids, but when i swallowed food, it would just stay at the top of my throat. can anyone say anything about this? cause this worried me a lot..... has this happened to anyone else?
