What's the point of 1 or 2? If you're completely honest w/yourself, you want to get smashed, right? I did anyway. A couple is just a tease of the " real" buzz you can have.
Don't go there. It is AWFUL.
Don't lie to yourself.
You can have fun w/ your friend w/ out a drink. You'll be doing your body a favor for your marathon. Good luck.
