IMO it's exaggerated that all the 5-MeO tryptamines would induce nausea but they do have a tendency to work on the body so maybe for other people a lot of them have that capacity. Though for me it is only 5-MeO-DiPT and that one was even tolerable, and yes if I come home tipsy and make the foolish mistake of eyeballing 5-MeO-DMT and snorting it then the result might very well be that it hits me like a freight train, I barf and lie on the floor wiped out at Jupiter gravity being steamrolled like an Italian pizza. 5-MeO-MiPT did a number on my physically but no nausea, and no vomitus.
Have not tried 5-MeO-DALT yet, the reports don't seem to indicate that it is unreasonably rough.
Yes 2C-E is a bad one IMO, but I think I already said that I believe that not the compound should be blamed but the way the user handles the body load. Often similar tips are given to try and work with it. Though if you are too late then you might not find yourself able to even stand up and channel that load. Even so, you can still meditate while lying down. If you feel victimized, or too lazy to work on it, or you haven't a clue how to meditate... ok. Maybe you're fucked. But I also believe your physical condition when starting is also paramount - having slept well and eaten well, not too greasy, not too little.
A number of times when I took codeine, I just wasn't feeling it very well and unhappy with the result took a bit more. This can give me some real body load from hell like I poisoned myself. Screw working with body energy like with psychedelics such as 2C-E. More like negotiating with your body to please forgive your poor judgement and clean up the toxic spill on isle 5.
The first time I took MXE, I also drank on it and took a really hefty dose of 2C-C. (Definitely not all at T+0:00 of course). I got more dizzy than any theme park ride ever made me, like someone put me in a washing machine only it made me feel dirty rather than clean. All this got me extremely disoriented and at some point I puked in the attic but did not see it coming. I felt like I screwed myself since I had no intention of explaining myself to family, it started to smell bad obviously, and my vision was like a total soup even without dumping my stomach. I had a hard time seeing what the hell I was doing but I got the job done.
I attribute the nausea to the vertigo though, and the vertigo to the presence of alcohol in the mix. It still made me laugh now and then in between, like when I lost my glasses and had to put in contact lenses with an insane amount of visuals, finding my glasses again (kind of close by), deciding I could take out my contacts again only to realize my glasses were lost again. And a few repetitions, reduced to a slapstick idiot. The hardest part was putting in the contacts with those visuals. I kept yelling: 'are you KIDDING ME WITH THIS??!! hahahaha'.
Good experiment, getting so lost in such a familiar place, but one time was enough.
