Best cure for hang over .... don't drink

I HATE feeling hung over, hate it, hate it, hate it ... that awfull taste in you mouth that does not go away even if you ate your mother's WHOLE parsley plant on the kitchen still

The last hang over I had, I did the greasy fry-up breakfast (brushed my teeth 7 times ) , followed by some really strong painkillers and a whole day of sleep ...

This April the 2nd, it's been 4 years since my last hangover I remember vividly, because it was a gf's beachwedding and her gay friend and I had a drinking contest that we both lost.
