I remember Bucko long ago espousing the idea of swallowing a tblsp of olive oil to protect his stomach before imbibing--IIRC he learned this from a French winemaker. I also remember reading Jancis Robinson saying she took a milk thistle capsule before events--she wasn't sure how effective this would be, "but it couldn't hurt!" And just last night a friend at a NY Eve gathering mentioned that she'd "heard" that celery is good for your liver--I say "heard" because she's a bit gullible and picks up random tips from unscientific sources like Dr. Oz and Parade Magazine, not exactly a big thinker--so she and her husband ate peanut butter stuffed celery before they came to the party. Me, I just make a point of hydration--as close to 1:1 as possible.
What precautions to you take, if any?
