A glass of milk is a good idea as it lines the stomach, so does mashed potato, or a good vegetable soup (looks the same coming back up too!!) Or, drink Orange juice before boozing as it retains the vitamin c in your body.
Sweet tasting mixers with spirits helps the alcohol get into the bloodstream quicker too, so avoid those if you can and don't mix - eg. wines and beer, or spirits with wine. A chaser can be okay after a couple of beers but not too many....failing that just have a good fry-up the next morning and you're sorted!!
