Why not? I always do. I enjoy drinking. Just don't get completely legless and make a cunt of yourself. That goes without saying, whether you are into game or not.

I make sure that I am not using the drink as a confidence crutch by making a point to also hit on girls when I am sober. I have been out and drank only water and still k-closed a Swedish girl. However, drinking is fun and it gives you energy to open lots and lots of sets.
