Okay. Well, i have been an opiate addict for the past three years. I started snorting oxycontin, then shooting it. Then shooting heroin. Finally a year ago I got on methadone, took that for like 9 months. And i decreased every month. But then I screwed up again and went back to snorting oxycontin for a few months. And during the past few months of using oxy, I started having really bad palpitations, my blood pressure skyrocketed whenever i did some. I went to cardiologist and they said nothing was wrong at all. So i continued and it got really really bad. So I got scared went to Suboxone for a week. That made my health problems get better, then the last two nights it went back to how it was. So I quit the suboxone and went cold turkey. And for the past 7 days I have been on absolutely nothing. The serious withdrawl syptoms have finally decreased but now I am really depressed. But im scared to get on an anti-depressant because of my heart/health poroblems. So I really want to know what is the shortest amount of time my brain will start producing happiness again? This is the hardest thing I've been through and without the health problems from using I know I'd still be using. But I don't want to die. So will anyone please let me know how long will it take?
