Hi Elle!
Welcome aboard! I don't know anything about cocaine addicition but I'm sure there are others on here who do.
You'll be in good company here. Everyone's so friendly and supportive and their's lots of good advice. Check out the substance abuse section, if you already havn't seen it.
I'm an alcoholic and today is my 6th day on the wagon. I've always tried quitting on my own before (I don't like asking for help either) and it never really worked. However this time I'm optamistic and I feel that with the help from the great people on here I'm going to get better.
Let us know how you get on. Good luck.
