Never cured it completely, but this would lessen the pain for me
One big glass of water with a couple of spoons of Salvital, drink it down while it's still fizzing
Another big glass of water with a few spoons of Glucodin, enough so it tasted quite sweet. I'd sip on this while collapsed on the couch feeling sorry for myself.
Once I could stomach it, fried eggs.
Or, you know, pray to whatever deity you believe in and promise to never drink again
