I was prescribed an opiate pain killer for my leg when it was in pain. I took it every six hours for about 10 days, and i would take it even if i wasn't in much pain because of the general happy/good feeling it gave me, and because it would take away my anxiety. So.. is it normal to still be wanting to take it and craving the effect? Would this be like becoming addicted? Thinking about it most of the day and wanting it? I've even thought of extreme measures to get it, like breaking a bone or seriously injuring myself on purpose.
