Too true - it's 10 times worse having a hangover *and* responsibility.

Personally I find that having a dump can really help sort out a queasy stomach, although if it's *really* severe then a tactical chunder might be a better option. Headaches are only dealt with by drinking the appropriate amount of water, with a painkiller if necessary to help you through the re-hydration phase. Avoid paracetemol in favour of aspirin or one of the other liver-friendly painkillers.
