I had no headaches or the dreaded ketosis breath I bought a pack of ketosticks as i was so worried that i was not in ketosis - but definately was as of day 3 onwards. I drink between 5-6 litres of water a day and my CDC said that it must be this that has saved me from the rotten side effects!!!
Water's great!!!!!! - Porgeous (who has lost LOADS on CD and inspired me to do the diet) once said - The more you drink, the more you shrink!!! So i've always done my best everyday to glug the H20!! Think people in work think i've either got a bladder problem or an unquenchable thirst!!!!!
