I've overdosed on DXM once, as I documented clearly on &Z, and it was by far.. the worst and most miserable experience of my life. Needless to say I almost died, had an irregular heart beat for over a week.. nearly went insane due to my mind being literally fucked into near oblivion. And it all started with an upper respiratory infection.
It's almost hard to still think about it without feeling some sense of dread. But what I can re-collect is a complete absence of feeling for anything, devoid of all happiness, any perception that what I seen before me mattered.. or that it was even real. I can still remember sitting in the car during my first trip out of the house after the experience, and everything just seemed so... fake, almost as if it were made of paper.. flat... bleak.
With that said, I really don't think I understand the concept of ego death. Or I have been unintentionally relating it to an experience that was in no way similar.
And for the record.. DXM is not something you want to fuck with, and its incredibly dangerous.. You can have permanent visual damage, psychosis, serotonin syndrome, etc.. I knew I was screwed when I turned off the lights and the walls lit up with neon colored numbers scrolling erratically outward. I would have been fine till I felt my whole body go cold.. I advise people not to do it, even though people are obviously going to do whatever they want.. just always like to offer a word of precaution.
