My RN friend advises that the penalty for over-indulgence arises from the fact that alcohol is a dehydrating agent and causes temporary hypoglycemia. Thus the "folk-cures" of drinking plenty of water and eating sweets are well-founded. I have found, through limited experience, of course, that a double dose of the powder form of "Powerade" works best for me. It's a metabolite supplement (similar to Gatorade) intended for athletic types during matches, etc. My own athletic days are long gone, but the stuff is very helpful after a rigorous and hard-fought elbow-bending contest.
