When I have a mixed drink, especially one with vodka or any hard liquor, my chest starts feeling tight and I get chest pains. It will go away in about half an hour after I do t drink anymore. It doesn't take much to set it off, just a half a glass. I can have a beer or a glass of wine and no problems. I am 45, 150 lbs, 5'6" and have never been much of a drinker.
