Ivy, the headaches are caused by carb withdrawel---Posted by Carol E. on 9/13/99 at 00:00 (010907)
which can be as bad as caffeine withdrawel. It will pass in a few days. During the second week you may experience a bit of lightheadedness which is a result of your body getting rid of excess water retention which takes potassium along with it so be sure to take a potassium suppliment morning and night for a while. Eating something a bit salty like a dill pickle may help also. This also passes in a couple of days. Hormonal and metabolic changes are taking place during the first two weeks and after that things even out nicely and you will feel wonderful. I feel better than I have in 25 years. I'm down 40 pounds, and my PF improves every day, in fact, for some reason I have noticed dramatic improvement just in the last two weeks. I almost never even feel it any more. Yeah!!!
