Sleeplessness caused by Alprazolam?

Not me personally but i know a real kind dude, can fight chooses not to small little russian guy looks like hes about to knock you out but actually really kind.

I went to pop some xannies with him and i noticed, dude doesn’t sleep. He will stay awake a day or two just popping xans and fall into psychosis. His Gf told me he was saying stuff like "babe am i going to fast?" while in his bed at night thinking hes driving a car.

Before you say it, after he had a big fight with his GF after staying awake 24h maybe 10 xans deep and i calmed him down after getting there i told him to
stop lying and admit to using coke/meth/crack whatever. We went to a laboratory to get his blood checked. No stimulants at all.

I also took the same xans he had (original Xanax bars not pressed) and had the usual blackout with sleep also. Really weird on all ends
