As Cristina mentioned, all benzos are depressants. Only sometimes, according to the person, can bring a different reaction.
In other cases, like mine, smaller quantities produce better effect.
I went from 2mg to .25mg Xanax (I had to mention it. I'm proud of myself) and wake up much fresher that before. And get the same calming effect (I guess). Althought I only use it to sleep.
And some sweet day, when the Vistaril really carries on, I'll be benzo free. Did I mention they are highly addictive?.
Good luck.
