I had a dentist appointment last week which I always dread because I sometimes feel awful the days after. I only had my teeth cleaned but also had a fluoride treatment. That was last Tuesday and today is Saturday and I still feel incredibly weak. Anybody else ever have a problem with fluoride? Now in hindsight, I can recall as a childe having a raspberry gel fluoride treatment and went home and got violently ill (to this day I cannot stand anything raspberry flavored). Now I'm wondering about my toothpaste, water, etc.
