I had similar issue and gargled with seltzer water which sort of fizzed up and let me spit out the saliva. Only the small cans worked as a one shot deal because the bigger, more economical bottles just did not keep the carbonation high enough to grab the saliva. But I just bought 24 can cases - Safeway generic brand - It was next to the tonic water which burned my mouth when I bought one by mistake since it has quinine in it.
It can not hurt to buy one six pack and try it out.
I hope it works for you as well as it did for me
