There are quite a few successes for myself in Scientology. I had a large history of drug use before doing the purification rundown. The Purification Rundown coupled with the completion of the next step really took me to the other side. From a user of drugs to a person who realized he didn't need drugs to enhance his life. The other major gain from Scientology for me was the realization that I was much more powerful as a being than I had ever given myself credit for; also much more able.
