Thank you!
I hadn't expected anyone would answer my comment, much less that anyone would provide a concrete reference point that was actually within my experience. I have used MDMA and experienced the high you're describing. For reference, I was high enough that I felt it certainly would not have been a good idea to try driving my car anywhere, but not so high that I felt taking my dog for a walk around the block would have been at all risky.
I found it pleasant, and wished it would last longer, but I don't think it's anything I'd go for if i were only 10% as intense and came with all the twitchy/tweaker effects. The jaw clenching I got from MDMA was more than enough of that.
But, as far as this:
> See you're amphetamine tolerant. Give your 20mg dose to an amphetamine naive individual, and they will get the euphoria for the first couple days at least of taking it. The euphoria quickly fades, though.
When I said "never," I meant "never." I didn't experience it the first time I took amphetamine, the second time, or this morning.
I have experienced some mild euphoria from prescribed dosages of opioids in the past, and, as I mentioned, I've experienced the high of MDMA, so, I think I have some sort of reference point here, although I'm sure they're very different highs.
Maybe it's because the starting dosages my doctors had me trying out initially were very small. Maybe it's because that initial dosage was 10-15 years ago, and I don't really remember it well (which would imply it wasn't very memorable). Or, maybe I did experience some euphoria, but just couldn't classify it as such because of my limited drug experience thus far.
In any case, as you said, I am not amphetamine-naive anymore and certainly don't get high off my medication at prescribed dosages, or even somewhat higher than prescribed dosages.
Again, thank you for helping me understand a bit of the appeal of smoking meth, without actually smoking meth. :-)
