Goddamn. The Meph Mania has indeed set in (by which I mean the entire world seems to have turned on to it, not some kinda crackpot paranoia on my part...)
I can honestly say I've never had blistered lips, nose bleeds, blue knees, chest pains, palpitations or any of the other side effects others report here. Of course, it's a stim, so when I take it I pour my fucking life's story out to my friends, as do they, and we all feel washed out the next day. To be expected, isn't it?
Mrs Orange and I also haven't really had such mad cravings that we binge, either. That said, we do restrict our use to a gram between us in a session - and have any more of our supply locked up, far away and entirely out of compulsive reach (it also helps we don't live in a country where we can ring someone up and have more delivered - which means we have to plan ahead, make an 'adult' decision to indulge, set the time aside, choose a special occasion, and make sure we have the time, money and mental state which would make it worth looking forward to, as opposed to a spur-of-the-moment recreational indulgence, which has been the case with coke, after a few drinks).
For us, meph has been a good replacement for coke, which is (as is widely discussed here and elsewhere) shit these days. Meph has proven to be much more positive for us, and lacking in the morbid self-analysis and negativity which coke brings on after a session.
All of which is to say - don't take good times for granted. They're supposed to be special, not an everyday activity. Anything's dangerous in large amounts - mephedrone is already known to be dangerous.
Take it easy out there, people. We have one life. Live it right.
