you said you used to take 10mg before? then you have like a big tolerance if i understood right... i'd say a normal dose would be 2-4mg like said before (at least for me). takin a third bar you'll start to forget stuff.. but hell 10mg, that'd pass me out for sure
also, you asked for rec use and effects.. well, at least for me (and some other people too), benzos dont have rec value at all. when i first got my hands on them i tried to get high on them, but they definitely dont have a high/buzz (like alcohol for example). you know, take 2-4mg, you wont FEEL anything, but you'll definitely be more social, outgoing, chill (if you're shy, other people may notice you a bit different)... and if you start taking more... prepare to forget things, then black out and pass out..
i'll tell you the last time i tried rec with benzos (+alcohol), it was on a thursday night party. i had an entire tab of bars with me (15 bars). i started drinkin, the party sucked, then maybe i took a bar, then another.. bam, next thing i know i wake up and its MONDAY, and i dont remember a single thing and the tab is EMPTY... so... yeah...
