I'm in day 5 SS and drinking at least 4L of water a day. I drank a 2 or 3 pints of water at work before this, but hardly anything at home. I'm finding it really easy to drink so much more though. I bought a 1L water bottle that has markings at every 250ml, and I downloaded the iDrated app on my iPhone, then set my minimum daily water intake as 3.5L, which is still well above the 2.25L recommended on the plan. Every time I have 250ml, I add it to the app so I can easily track how much I've had, and it is making me drink more! I never go anywhere without that bottle, then I know I'm giving myself the best shot at losing the weight. The more you drink, the more you flush out the toxins in your body!! Good luck everyone x
