Really? How would you compare that to Yoga and meditation on psychedelics? I have yet to practice yoga asanas whilst tripping on either dissociatives or psyches, but I have done lots of meditating and pranayama with psychedelics, with incredible results.
Quoting a post from many pages ago because i haven't been to BL for some time, but had to respond to this in regards to my last and deepest - first true ego death experience ever - mxe trip of which i posted a too long to read trip report here some weeks ago.
Like escape20 said, It's really great. Feels to me almost like a must to do with MXE to gain the full experience and have it more "under control" in regards of the mania. I'm a beginner basically with yoga (have practiced mediation occasionally on and off for many years but only lately gotten more into it) but like i explained in my trip report; it feels to me that mxe is almost like custom made for meditation and yoga. I could try to explain it (poorly) here but i think it's better to just try it out for yourself. Summarized: MXE (and any dissociative also i'd guess, but with correct dose of MXE you can move around and do yoga) makes you sink so deeply into your head that it makes meditation feel like natural passive process. That goes for yoga as well and you can stretch your limbs and body so easy and get focused into the moves if you put your mind into it. But the thing that makes it so great is that you don't even have to put your mind into so much as sober, it just flows so flawlessly.
I would strongly recommend practicing those things to everybody who uses MXE and has problems with the trip becoming too manic. It helps massively with keeping yourself under control. You could take benzos of course, but i think that would take away the psychedelia of the experience, so i'd recommend the meditation/yoga.
In reagards to the batch issues, i have also had the fluffy off-white/whitish and more grainy stuff and can't say that they have any difference qualitively wise. I think tolerance, and our minds expectations (like psood0nym above said) and reasoning plays a key role in this aspect. I have learned first hand that tolerance changes mxe's nature very fast and very strongly.
For me MXE experince is extremely inspired by the days event's before the trip. Other dissociatives as well. I strongly recommed doing something... maybe active sports during the day, maybe going downhill skiing or something like that (even just taking a train trip), and then taking mxe (Not during the skiing naturally, that might end up badly?!). If MXE works for you like it does for me, you'll sort of relive those events during the trip but on a much trippier scale. I love that feeling of flying/moving in space that mxe causes more than anything.
i didnt mean by far "safest",(did i type that..i meant by comparison to some not all ) it is without dangerous, i stand corrected, i was being flippant. but in comparison to SOME of the stuff out there i stand it SAFER then SOME. looking at the Ethalphenadrate (however you spell) thread, a lot of people are going crazy with this stim and getting psychotic, etc. 2mmp etc. nasty stuff.
It's funny that no other stimulant get's me so totally psychotic so fast as MXE often does. It doesn't stimulate me in any positive way at all - i usually hate the comedown, it feels more like an overdose. Never had even a slightest hint of a positive afterglow that many tryptamines or phenethylamines usually always give me. The dissociative side (albeit short in regards to the afterwards stimulation) is so very, very great though.
Back to the first subject; I would love to hear if others have done meditation/yoga under mxe and what they have to say about it. Try it people!
edit.
So, does anyone else get a hangover from mxe at high doses? Did 300mg at night and was completley useless the next day.
Also, I dont get these people talking about holing off 100mg. I'm still pretty functional at 100mg. And I dont even have much tolerance.
Yeah i usually always get the same kind of hangover as from heavy drinking session. Drink lots of water. Although i don't really remember to follow that advise myself nearly half the time and just end up eating handfulls of ibuprofen for lunch the next day

tsk tsk tsk
If you don't have a tolerance and 100mg's doesn't get you holing, i'd guess it's a purity issue. Everyone's body chemistries are different however and many other things (set/setting) can play a big part also... so maybe try a different vendor or try taking it after a few days on a different mind state/setting?
