One of the biggest changes in my life from my involvement in Scientology came from doing the Purification Rundown. Doing this program of vitamins and time in the sauna, sweating out drugs and toxins I'd accumulated, had profound effects on my life in ways I could have only dreamed of. In my younger years I had used drugs; later I realized my mistake and stopped this entirely. But I always felt as if I could never fully regain the purity I'd had prior to the drug use. I still had residual effects from the drugs and was always in a regretful frame of mind about having "blown it" by doing the drugs. This program freed me from the harmful effects of the drugs. After completing the program I found I could study more easily, I was more alert, and I could communicate with others better. I felt like I was back to "ground zero" in my life and could move up from there. I don't know of any other program I could have done that would have achieved this.
