In getting the drop on your hangover, here's step 2 in my amazingly convolluted (though perhaps only just barely convolluted enough) seven step hangover cure. Enjoy, and thanks to all who weighed in on the previous post!
Check, then ignore. I had a two Advil hangover this morning, in fact, but sometimes it's easy to develop a three or four Adviler. I would say by all means, use common sense. Advil isn't that good for you, so it's unwise to take 4/day. But if you have a mind-crusher (or any other painful injury), it's totally safe to take more than the recommended dose.
