I am neurotic about having bad breath but find if you drink plenty of water things are fine - no-one has commented on mine and I work with teenagers who don't hold back!!!!!! As for the skin thing, I must admit I am aware of it, BO and not having it is another thing I'm neurotic about (the only things I promise I'm not a basket case or anything!!!!!!) and I have noticed more of a smell since starting, not bad just slightly stronger than normal, although no-one else has said anything!
Hope that helps.
