Not true, JoJo. Vendome is correct - you should absolutely be gently cleaning your tongue every time you brush. (Even better is a tongue scraper - you can buy these at any store.)
There are products on the market that oxidize the sulfur compounds in the mouth. If you can get some of this, it's well worth the price. And, some come in a gel form. If you put some gel on your tongue scraper and dental floss, this will help greatly.
Postnasal drip is one cause of bad breath. Make sure your sinuses are clear, and you could take care of part of the problem. Some women will notice bad breath due to monthly hormonal changes. Some medications can cause bad breath - including decongestants and antihistimines. There can even be a family history of bad breath - chances are great that, if your parents or siblings have icky breath, you will, too.
One misconception is that you can take a pill to relieve bad breath. This is false, because the majority of bad breath does not originate in the stomach. Very little of it starts here.
Something else to remember - unfortunately, everyone has morning breath! Some may have it longer than just in the morning, but everyone wakes up not smelling sweet. This is because the salivary glands do not produce the amount of saliva while sleeping that they do when you're awake. Everything "stagnates" in there during your snoozing hours!
Ethel's advice was great - proper dental practices are crucial to having good breath. Gotta brush, floss and see that dentist regularly!
