Well its all about how much you do. Like the poster above me said small doses will help you in that aspect bit large doses just make you sleepy so you can imagine it wouldn't be very easy to concentrate like that drooling everywhere
As someone with pretty much no tolerance to Xanax, 2mg makes me not even care and end up doing something else which seems way more imporant or who knows what. Xanax makes me black out in recreational doses and I honestly hate it now. No hate though, I've said enough, but yeah pretty much when used not as "prescribed" it makes people I've seen including myself to act incredibly stupid and not give a shit.
