Discovering the binge potential of methylone
Until recently, I always had a reasonably sane relationship with methylone. Sometimes, I'd have none for ages (two grams sat unused in my drawer for well over a year). At other times, I'd have it occasionally (e.g. every few weeks). At worst, a few years' back, I was sometimes tempted into taking it once or twice a week. But always at most around 250 mg in a night with no redosing after first peak arrived.
Then recently I got too into mephedrone, and then - finding its side effects unfortunate (compulsive use followed by extreme edginess and labile heart rate the following day) - stopped using mephedrone. But I found my pattern of mephedrone use (every weekend, with initial oral attack dose followed by excessive intranasal redosing through the night) transfered over to methylone (which I had 10 grams of), and then extended into using methylone every two or three days, sometimes two nights running, and using more each time. The 10 grams ran out in 30 days. I'm fairly sure tolerance to all its effects was noted by the end, with larger doses required to feel any stimulation or euphoria (and never the lovely feelings that methylone can produce to a less overexposed brain).
During this period of methylone-abuse, the main effect noted was that two or three days following each dose, I'd feel incredibly tired, falling asleep on buses etc. (more so, I think, than I'd expect from the lack of sleep; I've done shift-work in the past, so I can compare with that). Other than that and the developing psychological dependence and the lack of sleep itself, no major psychological problems were noted for the duration.
Following cessation a couple of weeks' ago (when the methylone ran out!), I've been fine: no cravings or massive crash, emotionally or physically. Whether I can go back to using it more sensibly in the future is another matter. I don't know; but quite possibly not: If I ask myself honestly what I'd do right now if I had some methylone available, I think I can say with some confidence that I'd use it to excess tonight.
Anyway, people's mileage may well vary, of course. This is just a personal experience I wanted to share of discovering the binge-potential of a drug I wrongly thought I would always use with some restraint.
