I am 19, and i've probably taken it around 16 times, plus or minus a couple. I don't crave MDMA at all really, it's like some best friend I miss after a while though, but I know is always there.... one of those friends who are amazing maybe because you aren't constantly interacting. I first took E about 2 1/2 years ago, and it seems like an age ago.... n to be honest, maybe I have taken it too much, for my age. I have waited at least a couple of weeks between using, and i've never gone totally wild and pushed my tolerance up an insane amount, I think the most i've done is about 300mg of MDMA in a night, which is a lot, and has "fukd n bombd" me enough to recognise it as a pretty unique time!
I just need a break from E to be honest. I haven't gurned in about 5-6 weeks now, and I think I may wait for a while before doing it again, ideally months and months, but at the end of this month i'm seeing Shpongle, n I "may" be tempted then. I don't think the magic has faded for me in some ways, but in others it really has... I know what to expect, and the slight cynicism about the E experience has set in. I haven't really used many drugs recently though, so maybe that's not something to do with E really, it's more just about me.
So nah I don't crave it, but if I could never take it again, it'd feel like a real kick in the balls..... haha. %)
