How do I quit taking goody powders?

[Thompson4mlb]

For about 15 years I have been addicted to goody powders. I take as many as 6 per day. I don't have to have a headache to take these, I can be sad, mad, lonely or just simply have them on my mind and I feel as if I need one. I have overdosed twice the last time their were signs of my organs beginning to shut down . I do want to quit but everyone wants me to just stop cold turkey and that scares me to death. I have no insurance for another hospital visit but my ears have been ringing for over a month so I know I have overdosed again that is a symptom. Should I go to the hospital any how or just try myself to taper off them? I want to feel healthy again
