Vaper's tongue, try eating a cinnamon red hot or using a menthol juice to kick it...or swish Listerine mouthwash... Or even putting echinacea oil on your tongue can help.. Or if all those sound too intense, vaping a citrusy sour juice can help too. It will pass w time I promise.
Fwiw, once I was well past the vaper tongue phase, I also had this problem on my drippers for weeks, til I figured out I had hot legs on my coil and the overheated Kanthal was drowning out the taste of my juices. I moved em closer to the posts and voila. Instant heaven. Loll
