I think you are having a dental visit flashback LOL.
It may be those artificial flavor compounds playing tricks. I've heard some people say that clove flavor reminds them of novacaine.
Yep, Eugenol.
i have experienced the exact same sensation! only in one flavor - blackberry from freedomsmokeusa. the cause(only diff between this custom bottle and every other i have bought) it is straight, or at least 80% VG. it is thicker, coasts my tongue and throat and has minimal flavor. lots of vape, but mutes my mouth and leaves a terrible dull numb taste
No I never vape like straight out or up. Its not the juice in my mouth, lol its hard to explain but if you have ever got a novocaine shot while getting a tooth pulled, or even the little bottle you can get at cvs. Its the same smell and feeling as novocaine. I wonder if it has to do with spiced juices?
