From what I have heard (correct me if I am wrong) first hand, is take 3-4 days off from daily living and wrap yourself in a blanket and face it head on. Not a nice ride, but at least you will be clean. I know it can be done. My son got clean like that after almost 3 years on that crap. Or you can go to detox, and get some help through it. I am not sure but, from what I have gathered, crack is not as bad as reqular cocaine use. Again, if I am wrong, please correct me.
