Dukoral drug helps travellers avoid getting sick

I found a link for a drug called Dukoral which is taken twice before travelling which helps eliminate some of the intestinal sickness people experience from travelling in a foreign country. From a posting I found on a newsgroup... "Dukoral is a raspberry, baking soda drink that you take a few weeks before you go to China."

Here's a link to a document that explians it in greater detail.
