It's fucking weird. It's alright in low doses, but it messes with me, in a really weird way, at high doses. I've had panic attacks, been convinced I was under attack, and cried uncontrollably for hours - not all on the same day, thank god. It should be used in extreme caution with serotonergics, as it reacts really badly, for some - with MDMA, meph, etc. It honestly scares me. Also, it's nothing like ketamine. Ket, I've loved, the dozen-ish times I've had it. MXE makes me panic, but ket doesn't. Ket just makes me want to go with it, but MXE makes me wonder if I'm going to enjoy what's coming next.
