I've never really done this drug in public, I always do it at night at home alone before sleep. I've never driven on it, and I've almost never done it during the day. A friend went a little crazy with his mxe, he was driving around on it and stuff, which I don't recommend. I realize it interacts with a different receptor system but to me I just pretend it's like being drunk in a way, for safety reasons. Anything I wouldn't do with alcohol or when drunk (not that I ever drink anymore), I wouldn't do on MXE. So I don't do it in the morning because drinking in the morning makes me feel like shit, and I don't ever do it when I have to go out at all.
I wouldn't be surprised if it's quite safer than alcohol though.
I had this discussion with my friend the other day. On alcohol, when pretty drunk, you're liable to stumble around and bust your ass / get hurt. On a wobbler dose of MXE, you're likely to feel similar, and stumble around and stuff while wobbly - BUT - generally you will somehow make it out of the wobbly part unscathed, without seriously hurting yourself. Maybe MXE has special safety magic to go along with it's mania inducing properties haha.
