That's a tough one. It varies from person to person. I've been LCing for 18 months and I still have BB sometimes. But not nearly as bad as it was in the early days.

But welcome it...it is your stinky friend. It means things are going well (or that you need to brush ).

If you do a search on the topic of ketosis breath or bad breath etc., you'll find a zillion threads addressing this situation.

BTW, one of my favorite bad breath stories from the forum was a member who wrote that her husband returned from a business trip, leaned in to kiss her hello and said, "Well, I can smell that you stayed on your diet while I was gone!"
