Well, there is a crossover between mental release of inhibitions and holy shit my body just got dropped to the floor, I need to go to sleep now.
It takes the tiniest bit of most benzos to drop me in about 15 minutes.
Some paradoxical effects are natural, some are learned. I recall the first time I took two reds (for the youngsters, it was the premiere barbiturate - secobarbital) it had a very fast effect and most people who take them find that they had to get to a couch or bed or floor in very short order - and then they woke up in the exact same place 6 hours later. The game was to resist, to move around, to sit up, to force oneself to fight that drop and sleep urge. Once that was mastered, then one could take two or three of the little devils and be quite wide awake in a pleasant drunken state. One couldn't get that drunk on liquor without throwing up but with seconol, it was great fun, no spins, no nausea, none of the bad effects of loads of alcohol - all of the pleasant ones - and it didn't need to be nursed along like alcohol, having to continue a maintanance drink an hour or so.
The paradoxical effect is regularly employed when they give hyperactive children... a stimulant - that is counter-intuitive but it seems to work.
the same paradoxical effect was to be had with ludes. Many people simply fell asleep, but when keyed into the intense euphoria, folks would become hyperactive - even to the point of doing things they knew they should not - like drive.
Many of the Benzos have that same effect of exhilaration, of motivation, talkativeness and he like. When that paradoxical effect was ingrained the effects are never the same as they are for others.
I made the mistake with xanax of using it for sleep - now, when I take them, I fall asleep, but clonazapam, diazapam and some of the others will get me going,only subsequent and frequent dosing will finally have me succumb to sleep.
