Aside from the tried and true hair o' the dog treatment, which the gentleman in the photo seems to have planned ahead for, the local remedy I've always found reliable is a bonghit followed by a long hot shower, followed by a few more bonghits and a nice long walk in the rain.
Cheers, folks!

Wake up early-I always wake up at 7am weather I have to or not, take ibuprofen right away, force down entire large glass (or 2) of water, now go back to sleep and let the water and medicine do their work. You probably will still feel woozy when you wake up but not like worm-ridden death. This works for me probably 8 out of 10 times.

From your friend and mine, wikipedia (which has a pretty interesting hangover page):

Taking a dose of ibuprofen before sleeping can supposedly reduce hangover effects dramatically; however, the truth is that long term (longer than two weeks) use of ibuprofen increases the risk of stomach ulcers. Mixing ibuprofen and alcohol can cause stomach irritation and bleeding, and is highly recommended against. The adverse effects of alcohol are amplified when ibuprofen, which also can cause trouble with the liver, is taken with it. In fact, most medicines should not be taken with alcohol, so it is best to consult a medical professional before using this supposed "remedy".

Couple of Trader Joe's multi-vitamins before sleep. Breath is a little funky when I wake up, but otherwise works like a charm.

What about a blowover? Getting wasted, blowing some rails then drinking way too much because you can't tell you're drunk anymore. That shit hurts. Mega.
