Does anyone have dry mouth?

Does anyone that uses an Alginate have a dry mouth? I’ve been using Khelp since 4/3 and I have a dry mouth. The doctor does not think it is from reflux or Khelp. I’m being tested for other things. It’s really annoying I brush my teeth several times a day I’m careful about swallowing and food doesn’t taste the same. My tongue is affected the most.
