I'm on day three of doing low carb, and am finding it easier than I anticipated. A bit of a headache this morning and I fully expect to have a real horror of a day in the next few days. But so far so good, I'm not hungry at all and not even tempted to cheat. But. I need to pee All. The. Time. Which is doubly awful as I pulled literally every muscle in my body doing the shred on Monday so walking up and down the stairs is a real feat. Is this normal? Is this just my body getting rid of a load of fat ? I'm not drinking any more today than I have been the last few days so it's caught me a little by surprise.
