Caren, a lot of people experience discomfort in the first few days on Atkins. Detoxing, carb withdrawal, caffeine withdrawal -- it's to be expected and it will go away. The amount of time and discomfort vary from individual to individual.

I didn't have headaches. I felt very tired, but didn't have the headaches, so I don't know if this works, but in one of the low carb books I read (blush; I dont remember which one!) the doctor author said she suggested Alka Seltzer Gold to her patients who had headaches.

Drink lots of water! And, last but not least, cheese can trigger headaches in some people. If the headaches are really awful, maybe cut out the cheese for a day or two.

I hope other people who had headaches with more practical advice will chime in.

Welcome!
