I'm not struggling with the water to be honest, I'm actually finding I'm quite thirsty. But then, I always had a cup of tea on the go. I find if I've always got a drink in front of me, I'll just gradually sip away at it and before I know it, I'm at about 1.5l by lunchtime.
I've not tried any of the bars yet, just the shakes. What's your fav so far?
