what is the risk of blacking out of alprazolam if taking in .5 doses every 20ish minutes? i'm at 3mg so far, started with 1mg and have been adding .5mg every 15 to 30 minutes. i feel like im starting to feel the effects but not majorly, kind of woozy and stumbling, but my cognition seems fairly normal. would it be a subtle decline into passing out or could the next .5 do it
