I want to be honest. Like I said, I quit opioid replacement therapy 5 years ago and everything else before that. Last night I IVed oxycodone. I would have wanted heroin or morphine but they were not available. I did it out of being so frustrated with my depression, suicidal thoughts and anxiety and was curious on how it would feel like to be on opiates after all this time. I never liked oxy in the past and only did it if nothing else was available while being dope sick. I did not like it last night either. Besides I got almost no effect although I took a ridiculous dose (100mg, starting with 20 to be safe) for someone who is supposed to be without any tolerance. Now I feel like shit, physically and mentally.
