I can honestly say I have not been drunk in my life ( over 60 years old now) and have never got a buzz from drinks. I have in the past drank a whole decent bottle of wine at lunch in two hours and that has never had any effect , was able to go back to work and do a good afternoons input, ( well you know what I mean ) I can know drink six to eight whiskies with no effect at all. My wife says it can't be any fun but I have never given it any thought. Not proud of the fact nor do I drink and drive etc as it can be a problem as never feel that I can't drive . Can be very tricky. I also have Diabetes, used to work in a pub in my early years and liked a drink but never been drunk.
