I completely understand where you are coming from! After about the third day of atkins, I noticed this funky smell while sitting at my desk at work. I kept looking around wondering who was the source of the offending odor. Then I realized it was me! Talk about embarassing! Ugh, that's the part I hate about atkins. I tried drinking water, mints (but I don't want to add too many carbs), and celery. Finally, I decided OH WELL. I brush my teeth a lot during the day, but I figure I can sacrafice a bit of bad breath to be thin!!!!
