I'm on both sides here. I think if you NEED something like alcohol for a certain purpose, you probably ought to reign that in, but I don't think that a drink or two at league to unwind will destroy my family, life, or cause me to kill anyone . .
I used to need a few drinks to calm my head down so I could bowl, now I don't, but one or two helps. Some people have extra routines or rituals, some take a few aspirin or ibuprofen, some drink a certain kind of pop or an energy drink, etc. The very nature of alcohol is to relax you. Just like anything else, if taken to extremes, it will be dangerous, but there's a big difference between needing something and using something to your advantage. If a drink zones me in, I'm going to have one. Not because I need it, because it helps.
