I just have to say that since being on Atkins I do not wake up with a headache. Before starting Atkins, I always woke up with a headache. I used to hate to get up. Now I feel much better and have more energy in the morning. I was never a morning person to start with, but the headaches made it much worse. AND, I did go to bed around 10 or before every night. It wasn't from staying up all night. I wonder if it could be from the foods I was eating before?? I have only been on Atkins for 9 days and feel so much better. My cravings are even starting to change.
