Ephedrine is an ethanolamine derivative just like cathinone metabolites, they tend to have strong cardiovascular effects which I agree can be uncomfortable and worrisome and can ultimately be problematic as is seen with e.g. mephedrone binging.
Yeah tried ephedra when it was still legal and found it useful for parties but then again I had limited experience or other drugs available to me at the time, looking back it's an inferior product in my opinion... I wouldn't go partying on caffeine either, although that at least isn't unsafe.
MDMA can make one pretty mellowed out, it's not always that stimulating. So the lethargy is not that uncommon and I don't think it's a sign of any real issue.
I don't know what you mean by mescaline's stimulating qualities being a bad combination with psychoactivity, why? (yes it stimulates the sympathetic nervous system most likely but many psychedelics do and it's fine)
You don't
have to address the feeling, but in my experience/opinion (and it seems others arrive at pretty much similar conclusions from what I read) it begs you to "open up" rather than suppress it. I usually give examples of meditation, freeflowing dancing or yogic practices (some martial arts types are really good, I practiced pencak silat which is meditative and graceful rather than some aggressive krav maga blows or jerky movements).
But obviously having sensual / slow sex is excellent for both the release of bodily energies as well as emotional / empathogenic connection.
For me personally I doubt I would find mescaline ideal for festivals per se, because my experiences (at one of my own previous homes and another time at the very beautiful home I grew up in) were very delicate and personal. However MDMA can also be that way and is still of course a good party / festival drug. But, while mescaline is not like traditional psychedelics it can still put you in incredible states of consciousness some of which I would not find appropriate for a party, but maybe at lower dose yes. Not sure if I would find it a little bit of a waste that way, I couldn't say. You could try it.
I've taken LSD before at parties and festivals and that too can be borderline "inappropriate", if some parts of a strong-ish trip are such an experience of their own that it distracts from being at a party. Again, not much of an issue at lower doses, but there aren't all that many psychedelics or empathogens that would be bad at a festival at low doses.
Going up in 50 mg increments from 50 mg is very conservative, I have taken 300 mg and 450 mg (staggered) and found the experiences subtle in some ways and powerful in other ways. But the prevailing feeling is that I would find anything under 250 mg or so annoyingly low.
But I know you're very careful about all this, and nobody should really tell you not to be. I just wouldn't be surprised if it turns out to be a bit of a waste of time and material. For a healthy person just taking mescaline, there does not seem to be any evidence whatsoever that it isn't safe.
If you're talking about taking 1000 mg, well then I'd start to wonder what it does to the body, even though I do not know of reported health problems.
Let's see what erowid experiences labeled health problems entail for mescaline and cacti.
