Gargle, rinse & spit with club soda, aka carbonated water. It's a little uncomfortable from the carbonation, but it works pretty well. I went through a few cases of 12 oz cans. It isn't a drug & there are no side effects. I had tried a lot of different tussin based brands, but did not care for them. I think it was because you have to swallow it & I was pretty nauseated from the mucus to begin with. Different things work for everybody. Erik
