I really messed up on Tuesday. It was a terrible day, and I broke down and had some carb stuff. It wasn't a total disaster, but yesterday (the day after), I felt horrible all day!!!! I work from home and since I've been doing Atkins, I've noticed that my concentration is so much sharper and my energy is higher. Yesterday, I could hardly get my work done. I just felt like a slug all day! I went back to induction levels, and already feel the difference today. I was back in ketosis this morning, so I guess I didn't do too much damage the day before. I hope this is incentive to keep me from doing that again. Anybody else feel horrible the day after consuming carbs??
