I, too, experienced that addictive tendency to a shameless extent; this stuff got me worse than any opiate or opioid I've ever touched, and *far* and away worse than Ketamine, Cocaine or even Methamphetamine. I went through several ounces (4 1/2 if I recall correctly) of Methoxetamine in about five months. By the end, I lived in order to come home at the end of the day and lose myself, and I came to abuse the drug continuously until several hours (or less) before my next major obligation like my job where I could not afford to be fucked up at all. In fact, the job was the only obligation that I would stop for, and I ended up losing the job in the end, too - as well as my three-year beloved relationship. I'm still f*cking heartbroken over that - that pain seems to know no end.
It was interesting for me to hear someone mention in the Big & Dandy MXE Thread that how the use of this drug can leave one egocentric, yet completely unaware of that fact. Drug-induced narcissism. I have been clean off all street drugs due to the consequences of MXE abuse for almost seventy days now. I'm still not back to my old self.
The world I had been living inside for so long had warped into a brutal tug-of-war between what was left of my conscience and hedonistic escapism. So, too, am I still experiencing marked cognitive deficits that are far and away worse than when I would use 200-300mg of MDMA 4x/week for months on end, and that really scares me. Sometimes, I wonder whether or not I have incurred some form of irreversible brain damage that has yet to be discovered as a consequence of gross overindulgence in MXE. While I was on it, and especially during the brief periods of sobriety between binges, I noticed I had developed most of the symptoms of schizophrenia: delusions of grandeur, paranoid psychosis, auditory/olfactory/tactile/visual hallucinations (again, when not on the drug), suicidality, depersonalization, anxiety, irritability... I mean, it was intense. And this isnt even to mention continuing deficits in relating to other people, controlling impulsivity, encoding and retrieving memories, lack concentration and motivation, anhedonia...
But as the OP said, this isn't meant to be some scare tactic. MXE has the potential to be a wonderful tool for some. But I shall never be anything less than brutally forthright about how much destruction my addiction to Methoxetamine caused my life. It had the truest consequences of anything I've ever been majorly addicted to, and I was using it with complete abandon from reality and in order to abandon reality. The MXE dissociation became my reality, too, and that is definitely worth trying to convey for those out there that may view this as just another "once-in-a-while" dissociative psychedelic.
Moderation was never my forte when it came to drugs with severe potential for addiction, but Methoxetamine... brought me to my knees. And I'm still crawling.
