I know the atkins book says that when you produce the ketones, that your breath will have a different "scent" but how bad is that scent?

I can just taste it in my mouth....I can imagine how it smells!

I have some chewing gum that is low carb, and i use the mouthwash in the morning because even brushing my teeth 3 times a day does not help the "taste" of the breath.

Is this normal? and if so, how does everyone else control it?
