Honestly. This stuff can be pretty addictive. I have been using this substance for quite a while now, more then a year, and constantly had my use under control (like 2 grams a month max. on 1 or 2 occassions, sometimes maybe a little more or less).
But when handling large amounts ... this stuff can get pretty tempting, also because it's so damn cheap. Normally I am pretty good at keeping my use under control, but the past few months I started going a bit overboard. I seized usage for a while, before I might get addicted. I can imagine people can seriously get addicted to this, I have tried a pretty large amount of drugs in my life and until now only nicotine truly lead to an addiction.
I'd say it's on par with coke and amphetamines as for addiction. Can be nice, but take care with this one. Especially since it is so wide available in damn pure forms (compared to street drugs).
And funny to hear about those brain zaps ... After a heavy weekend I get the same thing on monday or tuesday. Often combined with some form of sleep paralysis, when I lay on my bed I sometimes get in a state in which I can't move and am half awake .... it's pretty damn scarying and it takes a while to get control over your body again. Last time this happened it was after a heavy weekend and while taking GHB, I was sitting behind my PC and slipped into a drowsy state ... had no control over my musscles anymore and saw my head bending over. I was hanging there with my eyes closed, everything dark and my head bent over. I felt really anxious, as it feels like you are constantly falling and can hit the ground in an awckward position any time.
Never had anything like sleep paralysis before. It is said that sleep deprivation causes this, but the funny thing is that I never binge on meph. It's not a drug that makes me stay up all night. Well, maybe stay up all night lol, but go to bed in the morning ... I never feel like this on mephedrone. I have been awake for 72 hours with amphetamine before, and that never caused anything like this. Not really worrying, but very weird.
humm.
