yeah im the same. like ive nearly got my first litre down, and im about to have my first one now, then the second at around 3 or 4 and then at about 7 or 8 my third one!...keeps evening snacking at bay!! x
First shake is about 7.15, second one around 1ish and the third could be anytime between 6-8pm. I drink around 1 1/2 litres of water at work and maybe a coffee and then at least another 2-3 pints of fizzy water in the evenings.
