Ok i need a way to make foam come out of my mouth. I know alka seltzers with a swig of water does the trick, but theres aspirin in the alka seltzers and im going to be doing this quite a few times a night. Im not planning on swallowing it, but i know after doing it a lot more than likely im going to have a healthy dose of apirin. are there any other health friendly ways to do this??
