One of my hobbies is cooking (the others; jazz flute, outsider art, and mahjong....*wink*). I came from a family entrenched in all things epicurean (well, regarding food that is...lol). My father had been a chef for a while, and has been a wine connoisseur (admittedly, self-proclaimed...hehe) for most of his 78 years. So naturally, I gravitated towards such extravagances. So food and drink became a mainstay with me. For some years, I have been able to counteract the "side effects" of these two indulgences, since I was an avid cyclist and hiker. But, after my plantar fasciitis problem this last summer....blah! I really need to temper my "hobby" LOL.....expanding middle, and backside...yeesh! XD
water and food (especially water) will help keep hangovers at bay, generally. If you still feel bad in the morning though, start with fruit. Your body will be craving sugars, and best to give easily processed sugars like fructose found in fruits. And again, water, water, water.

All else fails, greasy food, and yes......hair of the dog if nothing else helps.
LOL...giving advice on hangovers to those that don't need it. DOH! *smacks forehead* >.< XD
