as long as you don't feel like you're going into respiratory depression, nodding (falling asleep) all over the place, barely able to function, then i think you will be fine.
if you've got a friend there to look over you that would be a bonus. otherwise a family; you could tell them that you're not feeling too flash and get them to check up on you periodically.
though you say you're only mildly buzzed i would assume you'll be a-ok.
