I would suggest trying a very good Colon Cleanse and taking a good probiotic three times a day. I am taking Colonix (a three month colon cleanse) and it is an excellent product. I just started it, so I'm hoping it does wonders for me, but you could look it up on the internet and read the testimonials. There are some posts stating that it cured some people's terrible bad breath. I would also limit meat, and eliminate white Sugar and white flour products. Stick with it all and be patient. Don't give up. You are too young to quit trying. Make 2007 the year your life starts over again.
