Well I found out that what I have isn't actually vaper's tongue. It just kept seeming different because I had a metallic taste in my mouth and I couldn't really taste my food either, not even something hot. So last night I started thinking about when this started. And I realized it was a couple of days ago when I ran out of my regular mouth wash and started using some Crest Pro Health that I got on sale to try.
So late last night I started doing some googling and was shocked to find thousands of posts by people who have used Crest Pro Health and their taste buds were dead for weeks afterward. Plus some people had a lot of other even worse symptoms. Evidently, this has been going on since 2007 when the product first came out, and yet they are still selling it. I dumped the rest of it out, but I'm pretty mad about the whole thing. Still no taste this morning. I just hope it doesn't take weeks like some people were saying.
