As a general rule I would have to agree with you. There are extreme cases though, like myself, where I think drinking at the table actually gives me an advantage. I wouldn't advise this to anyone unless you have severe anxiety, which I do. I am so anxious and panicky during live poker sessions that my hands will shake really bad. Because it's impossible for me to just "calm down" I find the thing that works best for me is to drink literally 4-5, sometimes 6 beers. I don't get drunk really. It just kind of levels me out and I'm calm and I can focus better. Just a thought.
