What could I be allergic to in diet Dr Pepper?
So I've been having something really weird happen the past 2 weeks. At work I've been drinking diet Dr Pepper (which is a switch from Diet Coke). I have never had a problem with it before. Now, when I drink it I get a burning sensation in my mouth, followed by hives on my tongue and lips. At first I thought it was due to antibiotics, but I stopped them over a week ago. I was feeling absolutely fine until I started drinking the diet Dr Pepper at work. This doesn't happen with any other diet soda.
I have an appointment with my allergist on Friday, but just curious if anyone had any ideas?
