ive been rolling a lot lately since I'm on methadone/not doin street opiates anymore, so I might give GHB a try at the end of a roll.
I really really regret shooting MDMA though. It caused the only abscess ive had in 10 years of IV drug use, and I am positive it contributed MASSIVELY to me "losing the magic." I went overboard with MDMA when I was in high school so that partly contributed to it, but I could still roll really hard up until a couple years ago, pretty much when I started IVing it. Every time I did it for a couple years, I IVed it, and it is an AWESOME feeling, you roll SO hard, but now I'll take 400mg of really good molly and be underwhelmed. Other people I'm with are splitting a gram between 4 people and rolling harder/longer than I am taking a fucking gram (and ive never been on SSRIs or anything like that)
