I will admit to enjoying a beer with my dinner from time to time, but that's about it. I will drink more quantity at home on a rare occasion. If we are out and I choose to have a beer with dinner, I'm not armed.
TX law states that you cannot be intoxicated while carrying. They don't elaborate on the intoxication level either, so that's left up to the officers discretion, which can or can't be in your favor. No since in chancing it if ya ask me.
