Biot�ne has a mouthwash. It is enzyme based with no alcohol. I used it in treatment and was given a sample by the treatment hospital.

You might want to try a little room temperature bubble water like perrier or 7up. I would only try a little bit a sip or two to help churn and dissipate what is sitting in your stomach. The bubbles will give you a good burp to rid your stomach of what it is holding onto. Go easy on the bubble water though to not put strain on your kidneys.
