Quit. First of all...you should proud of your clean time. And, remember that coming off coke and early clean time is a time of great anxiety. They say coke is not physically addictive, but does cause anxiety when the person stops using. Stevie Nicks is a good example of this. But, in her case she was SO anxious going without coke her Dr. put her on Clonazepam, a tranquilizer...then she got very addicted to Clonazepam, which is a controlled substance...then she finally got in rehab and came clean from the Clonazepam and she is an inspiring example....she has been clean and sober for years now.
Anyways: Don't know what my point is, but don't give up looking for answers. And, you cannot always tell how good a Dr. is just based on reveiws. Some Dr,;s deal with really really really complicated cases, which may have some effect on how "successful" their treatment is. Just something to think about. Stay close to SR in the meantime. We're here for you and care.
