Strange sensation on palate

So yesterday I rushed to work without eating breakfast. During my break I felt like eating something sweet(I know I shouldn't give in) but I did and ended up eating 1 pack of Justin's Peanut Butter Dark Chocolate cups. Later on I also had a gluten free cookie. Driving home my palate felt kind of fuzzy as if there was a coating. Only on the sides though and I also felt coldness on the palate. It's a very strange sensation that I used to feel when I was on the antibiotics. Could it be Candida? Virus? Or food sensitivity??
