I'd love to see some quantative research to follow this up; something along the lines of;

A demographically representative panel of 200 adults were gathered and, over the course of an evening, were given 4 pints of lager, 3 vodka and tonics and 2 shots of tequilla. In order to maximize the impact, no food was consumed over the course of the evening other than a few canapés and some crisps.

The next morning, 100 were given 2 bacon sandwiches, while the other 100 were given a control breakfast of a croissant. The test subjects were then asked to complete a diary every hour, stating the intensity of their hangover on a scale of 1-10, including metrics such as "headache", "nausea", "inability to concentrate" and "tiredness."

Now, who can I get to fund this party, er, "research"...
