I picked up some GHB last summer, I had always wanted to get ahold of it. GHB, of course, is quite non-toxic. I was addicted to opiates for 10 years, it almost ruined me. I got off, 6 years ago. I've kept doing drugs, I've skirted the edge a couple of times. I would say in general I struggle to not be a drug addict, though I haven;t gone overboard since opiates. Except for GHB. I got like 200 grams, and did it very nearly every night until it was gone. I constantly broke my rules, it happened so fast. I had very little control over it, and when it was gone, I started shaking and I was feeling so bad. I ended up using phenibut to get past the withdrawals and then a long, slow process of weaning off phenibut (which I have done before), and finally a bit of gabapentin. But I still think about it, I loved GHB, so much I put it on my "can't have this" list. From what I understand, BDO is basically like GHB, but way more toxic. Besides the toxicity though, it's a hell of an addictive drug. Nothing has grabbed me by the balls like that except opiates. So euphoric and moreish.
