This is what started my downward road. I was a straight computer programmer, I got migraines, they gave me codeine. Anyway I took 3 and not 2, and my god I felt slightly sick and I was high as a kite. I ended up getting 50 pills from my doctor every 6 days for over 2 years, when i told her i was addicted she did nothing. So I buy over the counter and DIDNT EVEN KNOW ABOUT DISTRACTING CODINE FROM PARACETAMOL. I then found nurofen plus, and no I did not know you only had to bite it , the binder, and you got 2 pieces, 1 codeine, 1 ibuprofen. When I found out about that I had to go to old stores and buy old boxes. My gut blew to the ibuprofen, they gave me codeine in hospital for withdrawal, I discharged, went to my gp, he was different, he saved my hyde. He one day asked me if i was still buying over the counter, I responded no, and something then made me say yes. He turned stern and said if you continue to take those tablets, you will die. He prescribed withdrawal codeine 8/day, he told me to phone substance misuse team, and he said he wasn't happy he had to prescribe the codeine, he said if i dont go to the appointment, no more prescriptions ever from this work place. I have big respect for him. The substance worker wanted me on methadone, i said no thats for the other drug people. I ended up scoring 30 pills/day and they started reducing. The codeine then triggered panic attacks each time I took any so i came off them fast but I did try methadone, it did give me my life back. Some use it recreational, some use it normal. I cut my own down, and now and then id retake it. Its different. Definately good treatment. I tried the subutex before it got converted over, didnt work.
Just remember the kill range is from 500-700. I really think its 700 but females are different. Oh and thats including tolerance. If you are new to it, use your head, increase slowly and don't get addicted!
