15 hits of X? At 100mgs per pill that would be a gram and a half, no wonder you had problems! Meth won't cause you problems at 100mgs once a month, do 1500 and you'll screw yourself up, I'm guessing MDMA is sorta the same way. I've only tried it a few times, but it seems to me to be alot like dope, but sort of the mirror opposite, if that makes any sense. Like X is joy and light, and meth is darkness and paranonia, but sorta the same mindless euphoria. But I do agree it could be addictive, if you have an addictive personallity. I do, and I'm actually pretty cool with it.
