No hang over here, never had one, never will, I stop when I get the Buzz & sleep 8 hours or more, it also helps to drink the whisky straight, no sugar in the mixers & NO DIET SODA Ever, sip the whisky as it was made, or add just a touch of water , nothing carbonated, the bubbles & the sugar give you the Blach feeling the next day !OR do what a lot of people do, just stay all lit up till the liver stops working never have a hangover when you $hitFaced all the time ! hahaha Enjoy,Vince
