No Snacks, no sweets, no seconds. Except on Days that start with S. Too simple for you? Simple is why it works. Look here for questions, introductions, support, success stories.
I've been on it 8 days, I would say on day 3 or 4 I came home in the afternoon with a headache and didn't feel well, and I know I was hydrated. I've been better since then, so I'm not sure what caused it but I thought it could be my body "adjusting." Or I was just letting too much time pass between lunch and dinner, and my lunch wasn't big enough.
Hi Monica, Were you by any chance a coffee drinker, and cut it out because of added sugar or other snacks? That can cause headaches also. Good luck on NoS and with your headaches.
