Redheads also have a chromosome that makes it more difficult for anesthesia to work properly, so they need more of it given to them. Same with Novacaine, I've read. Do you find that that is true for you?

Although I am not a red head, I know shocking, my ex is. When she was here to get dental work done I was shocked at the amount of Novacaine she needed. She told me then this was the norm for her, even for surgeries.

So I am guessing yes, there must be some truth to it.
