My ex husband was using this crap at the very tail end of our marriage. I've never touched it and never will. I was naive and didn't really know he was even using, I suspected it but I didn't know for sure until the moron overdosed on it (that was after we separated, he had blown all of the money in my bank account, probably on meth, so we got evicted from our house and I felt that was the perfect chance to get the hell away) He was using while I was at work, and unfortunately had MY children in his care (they're his also but at this point he doesn't get to claim them in any way, as he is total douchebag and by his own choice is not involved with them at all). I should have noticed sooner and suspected something was up when he suddenly became paranoid about everything but by that point I was so fed up with him anyway because he wouldn't work or really do anything at all except mootch. I was working double shifts all the time, trying to make up for what he was spending. He neglected the kids and my youngest wound up with developmental delays as a result. Anyway, last I heard the loser has stopped using but as a result of using he has had to have stents placed, and basically has the heart of a 90 year old man. I don't expect him to live to see 40, and even at the risk of sounding like a cold, bitter bitch, I really can't say that I care.
