Yeah, it kind of seems like you ruined your tolerance by taking more than you needed to. Either way, the first time is new and you (and by you, I mean everyone) are naive and inexperienced with the drug. You can't ever get that back. For me, rolling has evolved and I am now much more in control than I was when I started doing it, because I'm so familiar with the high. Those kids that are wide eyed, hugging everyone in sight, and obviously rolling some serious balls at raves... you won't ever see me like that, because it's not like that for me anymore. But that's ok. Stop thinking about losing magic, I'm sure some of it's in your head. Just take a nice break, be responsible with your rolls, and you'll be able to appreciate them for a long time, despite the fact that they will never be as "magical" as they once were. I've been rolling for 10 years, and have abused it twice, but as long as I space them out properly and use MDMA as a celebration thing, I always roll, and I always enjoy it.
