You can tell if your in ketosis by a few symptoms, bad breath, furry tongue, bad taste in your mouth. You can buy 'ketostix' at the pharmacy and you test your urine, but to be honest, as long as your are sticking to it 100% you should be in ketosis from around day 3-5
Thanks for the feedback....does your wee smell because I have noticed that but no strange taste in my mouth and as I can't smell my bad breath ;o)
Can you have mints or how do you keep the bad breath at bay?
