I must have snorted about 250mg last time (over extended doses), which was absolutely fucking mental.
at that dose, it's nothing like the floaty euphoria of a k-hole. More like every semblance of reality is breaking apart, you have no idea who you are, or any sort of memory of what life was like before. All you know is swirling, twisted, distorted chaos. Visually it weirdly enough takes on the appearance of particles flowing and turning, oddly enough, into rooms. Fairly ordinary looking rooms. But the feeling is so, so indescribably alien, it's even nuttier than a k-hole. this 'crashing through alien rooms' lasted for a while until I ended up trapped in some sort of cellar, where it felt like I had to exist forever.
The first time I took a super high dose of MXE, I had a similar experience to that, with everything distorting and becoming completely alien, but this time it ended up with a profound vision. I realized the world was ending, and I eventually transcended, lovely and peacefully, into a mass wall of consciousness outside of time and space, where I felt the energies of my friends, family and girlfriend all with me floating towards the next phase of life. It was beautiful and magical, if not still a bit frightening to be confronted with something like that.
This time however, it was just alien, distorted, twisted, confused chaos. Fucking nutty, very terrifying but also oddly enjoyable too (can't explain it. just something about being so removed from any resemblance of reality.)
About 100mgs of MXE is enough to put you in a nice, floaty, near k-hole sort of state. Any more than that and it's just too fucking crazy haha, although can be incredibly profound if it goes well.
