Thank you, all! I decided not to get the waterpik because it's a little expensive. I also love to travel, and I want to find strategies that will allow me to do so. A waterpik would be bulky on the road. I maybe optimistic, as I am
not sure how much traveling someone with a PEG and a bad voice can do, but it's the goal I am working toward.

I was able to try Mucinex. It appears to be working.
