Although they are delicious, has anyone else had this happen to them?
After eating Hersheys Cookies and Cream bar (every time), my throat usually burns but it does not seem to be an allergic reaction?!....
I'm going with the general consensus, they are really sweet and that sensation has happened to me too. I usually will only eat a few pieces at a time and drink water when I am eating one so it eases that sensation.
I agree with everyone here that answered the fact that it is very sweet. The same thing happens to me; so I don't think you're allergic, just try drinking water or something while eating the chocolate!
