Don't do it. Very dangerous but I'll tell you a life story here.

Back in the day when I was younger I used to abuse benzos and drink. I'd get the tiny white 1mg Lorazepam pills, crush 3 to 4 of them up at a time and sniff it like a line of coke and chase it with a double shot of vodka. My experiences are hard to recall honestly, because I would wonder around so high and fucked up out of my mind that half the time I had no idea what I was doing. Total painless bliss is all I can recall, my mind trashed but it did feel absolutely wonderful and  obviously if I did it more than twice in one night I would blackout, not remember a damn thing. The more you do it, the more you risk dying from it. It is extremely dangerous to overuse benzos. These pills are easy to OD. Worse, if you get addicted to benzos it becomes extremely hard to quite, much like hardcore alcoholics having serious withdrawals not drinking booze. 

The withdrawals I had from benzos were absolutely fucking awful (much like hardcore alcoholism): you get physically and mentally sick without them, you can no longer sleep, you start to shake because your nerves have been damaged by the abuse and addiction, you can easily get PTSD from the withdrawals, non stop craving makes you climb the wall.... and even when the symptoms subside after a few weeks and you can finally go back to sleep? Terrible hellish nightmares. You wake up swinging and kicking, screaming and sweating. Fucking PTDS.

I did overcome the benzos and will never do them again. BUT AT A COST.... for over 20 years I became a binge drinker, an alcoholic to this day. I wouldn't have been able to quite benzos had I not substituted the drugs with booze.
