Before I stopped using it about a year ago, it was definitely MXE, that shit's better than coke & opiates combined. MXE was my worst vice though, I simply cannot keep a stash or it will ruin me for as long as the stash lasts...nobody I know is into it either, which is probably a good thing. These days however, cocaine would be my "had a bad day" drug, actually helps me view things from a more positive perspective, of course it has problems surrounding it as well, particularly it's fiendy/compulsive nature, but somehow it's very easy for me to stay away from it when it's not around even though I rip through it like a man posessed whenever I have it.
