BooBoo you lost that much in a week!! Wow thats amazing Well done!
I wouldnt replace the water i'm drinking, but black coffee is getting on my nerves lol. I'm also drinking peppermint tea, but the odd coke when everyone else is drinking on a night out would feel better than soda water!
I can't see the occasional coke zero doing any harm unless it makes you crave sweet things. Even diet coke can have that effect or any diet fizz. Coke zero has no citric acid which is better still for not affecting ketosis as you will remember perhaps from your CD days!
yeah that ole devil citric acid! I'm not a huge fan of aspartime ridden products, nor all the artificial sweetners, but I reckon sneaking a can of it on a night out would help me resist the vodka that normally goes with it!
