Would you carry while exhausted?
Fatigue can impair your judgement just like alcohol.
If you're willing to carry after a long day, carrying after a drink or two shouldn't faze you too much (unless it's illegal, of course).
Personally, I don't carry yet, but one beer (or even two, depending) doesn't affect me noticeably. I wouldn't get hammered while carrying, but I wouldn't be worried about a drink with dinner.
18 hours sustained wakefulness produces performance impairment = .05% BAC
24 hours = .10% BAC (Dawson & Reid, 1997; Williamson & Feyer, 2000).
People with mild to moderate untreated sleep apnea performed worse than those with a 0.06% BAC (Powell, 1999)
On 4 hours sleep, 1 beer can have the impact of a six-pack (Roehrs et al., 1994)
