well done to losing so much in your first week. I'm due to start on Tuesday.
About your breath etc... I have just read somewhere that one of our buddies chews sugar free gum, but.... a CDC said maybe she should knock it on the head as when she is chewing her brain thinks that she is gonna be eating and her tummy creates a load of acid to break the imaginary food down (my term of phrase not hers) and the acid just sits there as no food is coming...... phew.... soooo,???? I too am worried about the bad breath thing as I have read it happens a lot..... You can't go mad on mouthwash either as it can damage the old nashers. I hope it gets better for you though.
