I find it really hard to get the water down partly cause I don't like it and partly cause I'm working in the community and it's not that easy to find a loo!! However, when I have drunk the recommend amount I've had good losses and when I don't (like last week) I don't (I lost a pound). I've neva drunk more so I don't know but I do know u need to drink at least the recommend amount to see good losses every week. Hope that helps x
