Vodka to diarrhea
As a musician you know some tricks to solve health problems right before the performance. In inns there are a few pulls around, including vodka.
So if you are not an alcoholic (and no car drives) and suffering from diarrhea right before an important event, should approve a double vodka. It calms the intestinal flora within 2 minutes! Habs himself tried and the performance was really good. More than 4 cl is not necessary (and not recommended). Of course only useful if no other drugs were taken, otherwise more serious consequences!
