As BL said, 3 to 5 days usually, if you have very little / no carbs for the dew days before starting it could be slightly less, maybe kicking in at the end of day 2, but if you had a lot of carbs prior to starting (i.e. your 'last meal' was a whole load of bread ) then it could take a week to use that all up!
and yes, drink more water for the breath thing. I noticed in my first few weeks that my breath was terrible, though /i was having around 3ltrs a day of water - upped it to between 4 and 5ltrs + shakes, and breath is a whole lot better (still use the listerine strips though! guess I'm paranoid )
Hi all, Thanks for the comments.I guess I'll have to drink more which isn't a hardship as mouth very dry.I obviously can't be in ketosis as I was not low carbing prior to LL ,I'm afraid I went for it big style! Just a bit paranoid like you Pete re the halitosis as I am dealing with the public all the time.
