ok, I don’t know how it is in america, but here in australia it’s the law to have the number of standard drinks an alcoholic drink contains printed on the can/bottle. 1 standard drink is the amount of alcohol that the average person can process in 1 hour.
my maths goes as follows - remember, this is based on the australian system of measurements and the 4 schooners and 1 tinnie I’ve already ingested this evening…
Now, 1 can of full strength beer is roughly 4-7% alcohol and has 1.2 - 2.0 standard drinks (1.4 is by far the most common)
1 glass of wine (100mls-ish)has only 1 standard drink, as does 1 nip (30ml) of spirits (scotch, vodka, burbon, etc). On to your question…
1 six pack of beer (6 x 375ml tinnies/stubbies - 2.25litres - I’m sorry, but someone else will have to work out the imperial measurements) contains approximately 8.5 standard drinks. at the end of 3 hours you would have just over 5 left in you.
The equivilent number of std. dks. in wine is about 850mls. If you drank the equivilent VOLUME of wine, you would have had over 22 standard drinks - more than enough to get you pissed well into the next day. After 5 hours you will still have 14 drinks left in you.
Spirits is 1 std dnk per 30 mls (I think that’s about 1 fld onz). The equivilent number of burbons (or whatever) is about 255 mls (not including a mixer, eg coke). the equivilent VOLUME is not recommended, as it’s enough to kill you at a whopping 75 std dnks - that’ll get you shitfaced well into next week. If not the next life. After 3 hours you’ll either have had your stomach pumped and be on a saline drip, or you’ll have had your last rites.
<anecdote>About 2 years above me at high school school, a guy at a party decided to be intelligent and skoll (drink as quick as possible) a 750ml bottle of Jim Beam. He was clinically dead for a full 3 minutes before the paramedics revived him.</anecdote>
Now, there is always a personal factor involved. For example, red wine doesn’t have much of an effect on me (the two High Distinctions I have recieved at uni were written after drinking a bottle of quality Australian red), but a few glasses of white and I’m out for the count. Beer and coloured spirits (scotch, burbon) are about the same for me, but clear spirits (vodka, gin) get me rat-arsed. With the exception of Ouzo, but that’s just my greek heratige shining through 
I think that that’s answered your question. give us a buzz if you need to know more about alcohol. I hope that you understand metric, or else I’ve wasted quite a bit of time.
