Never used them or never got hooked? I've never not been able to stop. Just how I programmed myself. It was an epiphany I got at the casino one night as I was sniffing coke off the top of the toilet paper dispenser. "Can't do it forever" is what I thought. And that seemed to do it for me. Knowing I wasn't going to gamble, do coke, hangout with filthy strippers, for long b4 it ruined me.
