Yeah D9, the 1000 post limit isn't strictly enforced anymore. It still is in other parts of BL, but the last Social thread went well over 4000, near 5 I think before I guess some sort of size control was felt to be needed.
I remember before I was mod, we'd get all excited when there was no mod around and we'd see just how high we could push it. I think 1250-1300 was the highest attained during the 1k limit enforcement; oh those were the days.
I'd never advocate stims but if you're doing them anyway EPH is one hell of a stimulant (am I right it's illegal in the US?). It's not neurotoxic like amps either. But it's addictive like hell and only cocaine is more addictive for me (luckily I have it very seldom and only for a night/evening). I've never tried any fluoroamphetamines but speed (d-amp) is occassionally nice, especially since I get very pure stuff from my contact.
I was recently telling about how I wasn't touching amps or derivatives besides for fun occasions; well that didn't work out. Ashamed in a way, that's a definite sign of lack of control.
Anyways I find EPH to be a good stim, but I find one of the worst side effects is tachycardia; especially if taken on an amp comedown to potentiate and make it last longer. Also, if you actually take enough to get that EPH high going (which is amazing like you say), the comedown is horrendous, almost like MDPV in that fashion.
EPH is nice in that is doesn't last a super long time so you can take some around 8-9 at night and still get to bed around 1.
I'm a strange one in that I find d-amp much less recreational than plain speed (racemic amphetamine). Racemic amphetamine seems to give me a serotonergic-like high, that lasts a long time. It's hands down my favorite drug for active days out camping.
As for the rest of your post; I have never had a sedating psychedelic (sedating anti-cholinergics, yeah). I remember Roger telling me how relaxing 2C-C was, I took a modest dose, enough get passed that trip-threshold but certainly not strong. Well, relaxing my ass, I gave him shit because of how energetically high I was :D
Tryptamines seem to be even worse; I find them less relaxing than phenethylamines.
