I think Hollywood and any filming industry will try and dramatize anything and everything. Of course everything comes down to opinion. But the term "downer" can go a lot of places. People consider benzos downers. When I think about it they are anti anxiety/anti seizure meds. Yet without a doubt people love them.
It is my own opinion that they are not like any other downer though. And I would like to believe in a double blind test most could discern between other sedatives. I believe most people, even benzo heads would appreciate them. But my really big wish for us BL'ers is someday we can go to a buffet of drugs and pick and choose what we want to test.

Then we won't just have people telling us their own tastes. (hey I can dream eh?) There are lots of drugs I would love to try that I probably never will.
I do remember doing them in high school. I would take a lude before homeroom and then the first few classes stumble around as if drunk and feel sedated. By lunchtime most would wear off. So it is not a long buzz. Just hits fast and feels like alcohol. I believe Rorers were floating around more than Lemons but both were the same.
I only saw the Wolf Of Wall Street once. But Scarface a millions. Tony Montana: "Let her go let her go, another quaalude and she gonna love me again."
