What Causes Weakness And Dizziness On Usage Of Epinephrine?

Hello Doctor; How can I tell my Dentist to stop using Epinephrine in the freezing formula? I felt very weak, and was afraid of passing out in the Dentist Chair last Tuesday, Feb. 17th. I had to lie down on their waiting room sofa for some time, the receptionist refused to go on line and find out the anecdote, or what I should do to neutralize the effects......I walked for 5 blocks, and kept drinking Coconut Water to try to dissolve the effects......had a bite to eat......I have another appointment tomorrow at 11:am. I am hopeful the Dentist will take me seriously, and not use Epinephrine again......Can You Help, advise me in anyway......I am 66 years old, do not smoke, in pretty good health. Sincerely, K. Kallin
