Vaper's tongue is temporary. It will pass. If it doesn't pass after two weeks, make sure you see your doc, as it isn't vaper's tongue. Your post doesn't say how long you've been
vaping nor if you're a high-watt vapor or use very high nic...so I can't really make suggestions like "turn down the wattage/vape-volume and see if it makes a diff". But you could always try adjusting your
vaping too if it makes sense for your particular situation. Nic is a nerve agent.
For me it was a few weeks into
vaping and after giving up the tobacco. But it all came back. I actually associated it with tobacco cessation as much as with vaping, but that's just a guess. The logic at the time was "system is rebuilding and adjusting".
