Just don't fall for the "cures". I had vaper's tongue for about a week when I first started. People had me
vaping hot cinnamon
juice,
vaping the strongest pure menthol I could find, putting hot sauce on my tongue, eating jalapenos, drinking pickle juice and even straight vinegar, brushing my teeth and tongue over and over, and all kinds of other crazy stuff.
Someone even told me that if I put an unused tampon in my mouth and left it there for 5 minutes that would "cure" it. Don't believe 'em. Just wait it out, it will pass on it's own.
