The last time I rolled was about a year ago. Before that roll, there was a period of about 8 months without rolling. My rolls have really spaced farther and farther apart over time. I'm not sure if I'll ever roll again actually... MDMA has always been my favorite drug ever since the first roll, and there are very few popular recreational drugs that I didn't try.
My first roll was in April of 2000, and at that time I rolled about twice a month. I continued at that rate for about 6 months, then after that point it was about once a month which continued for a year. After rolling on September 2nd 2001 at a Crystal Method show, I decided it would be my last roll. I rolled only 2 times after that point, much later on. I think I'm done with rolling, there are so many incredible experiences from 2000 that I can't seem to recall now. =)
