Ahhh My old friend Jack, he is a Gentleman these days. If you have an oxy/acet set up a few hits of oxygen will cure any headache in seconds. Once the headache is gone just start on the coffee, water or what ever your morning drink is and triple the amount. I learned once on a house boat vacation that you can go a week without a hangover. Just don't stop drinking. Slow down the last day. I really don't drink enough to get a hang over but once every 10 years or so. Got to watch out for those women trying to take advantage of ya :<0) .
