Thanks on my 3rd litre so far and I always take litre to spin with me. Haven't even had tea yet so I'll def be over 4 litres today just hope can stay motivated to get through week one!
I dunno id question the water thing... there have been days where ive only drank 2 litres and next morning lost 2lb then days ive drank 3-4 litres lost nothing.... i think aslong as you drink 2litres plus i think ure ok.
