Once clean theres really no desire to use. By the grace of God i havent wanted to use IV heroin in over a decade. The last attempt getting off suboxone. The one time relapse wasnt motivated to get high.. i just was sick of being sick. Sweating and lack of sleep and appetite that lasted for months and months i wanted relief from. It terrified me. I know what drug use has taken from me.. including my best friend and brother. I never want to go back to that place.
