Just don't do what I did last Thursday!
My friend had a 14 hour day at work and was tired and pissed. So he called me and was like I'm going to the package store, were drinking!
So he comes over with a bottle of Captain 100 proof rum. This was about 8:30.
We start working on it and my other friend comes over at about 9:30 and has a drink. By 10 the bottle is dry and we head to the bar, to meet up with another friend. So now I'm on beer and probably had 3-4 Bud lights and a shot of tequila while at the bar. The 2nd friend who showed up called it an early night and left at 11:30, so my budy and his friend from work we met at the bar kept drinking. His friend is used to working 3rd shift but had the night off so he was ready to go at 12. We left the bar at 1 and since me and my first budy were in no shape to drive, his friend drove us to his house. Where we had a couple shots of jack, and a jack and coke, and finaly he drove us home at 3.
That was a long night, I can't beleive we pregamed by killing a bottle of Captain 100!
