Zombies...In the Potable Sense
1. Know your limit. That is, know what it takes to make you drunk. This of course varies with weight and age and tolerance for alchohol.
2. Learn what kind of drunk you are and indulge accordingly. Really, if being drunk brings out any of the nasty parts of your soul, avoid it. Nobody wants to see that. If you are a happy, silly drunk, as I am, don't seek it out, but neither do you need to avoid it. Just don't become so addicted to the feeling that you become addicted to the drink.
3. Everything in moderation. There's really no need to overdo drinking. It can be bad for some, but there are plenty for whom it is a relaxing form of "blowing off steam". Benjamin Franklin had the right idea here.
Most of all, if you suspect or even know, that you are prone to alchoholism, stay away. It will never be worth it. I don't mean to preach here, these are just observations made in a clear state of mind by someone with no strong opinion either way. Three simple rules and a bit of common sense that will lessen any number of financial and social burdens. In my case, I think the last drinking I did was at Christmas, at a party thrown by one of the educational establishments where my wife works. I had a few R&Cs. Prior to that, I think I had some beer at a Sci-Fi convention. Before that, in the summer while BBQing I had some hard lemonades.
What I'm getting at is that you don't have to turn yourself into a zombie to enjoy booze. It can be a way of life without BEING your life. We all like to think of ourselves as smart people. Surely the wisdom of these rules is self evident.
