so i got a small prescription of lorazepam for various reasons, but had a few questions i didn't get to ask my doc. and the information printed out was surprisingly vague. after taking one .5mg tablet, how long should i wait before: 1)driving? 2)drinking (not at the same time of course)? i have never taken this before and really just want to pop on in before i go to bed so i can actually sleep tonight. thanks in advance.
