Best hangover cure is to prevent one. Before you drink, during and after, pop vitamin B complex, and drink plenty of water. I have another friend who swears by this. Its never let her or I down. Last weekend, I may or may not, have had a lady guest here for the night. I kept pushing B's and water down her. The next morning, she was amazed at the lack of hangover. A slight headache. I gave some advil and more water, and she was go to go.
