Works for me
I have regular bouts of sickiness (long story) and have found that full fat Coke sometimes stays down better than plain old H2O. I put it down to the bubbles breaking up the surface tension of the vomit and releasing any trapped gas from under it, so all that comes up are burps rather than stomach contents. It needs to be out of the fridge ideally too, as the coolness helps reduce the discomfort of bile burns in the oesophagus!
