Too many times to count. Prob under 100 though. I agree with spacing them out. You get a better buzz if you don't have a tolerence. It's cheaper too. I was rollin 3 days a week for about a year and finally, I was at a party one night, and when everyone else ate there's, I just didn't feel like it any more. I had a great time that night and was completely sober! I stayed clean from E for about a month, but still partied. Then just as quickly as I had stopped, I started again, but it was a much better buzz, like the first time you roll. Plus, I managed to get high without spending $100. Since then, I learned to give my body a break every now and then.
