Strange question !
Yes. And I had weird "menthol"/peppermint feel on the back and sides of my mouth too.
I correlated it to taking my sublingual B-12. The only thing I can think of is that there are disintegrants/surfactants in the formulation to aid dissolution and absorption that must not agree with me.
PS. my B-12 is CHERRY flavored.
