Quoted from MK6PIN:I've enjoyed gallons of this stuff when on the islands.....possibly my favorite beach mixer...wicked headaches after for me, however.......
One of these and a B complex before you start drinking (never after drinking for the N-A-C) along with a couple glasses of water before you go to bed and anything short of a major binge, you won't have a hangover the next morning. If you binge, expect to just feel a little off. So much better than a major hangover though.
