the side effects like headache's and tiredness only are during the first week and they go. some people have noticed hair falling out and that. but once you are finished the diet it will grow back.
When i started cd i didnt have any nasty side effects during week one. i never felt more happier and full of live i had lots of energy. Im on ww now but plan to restart cd in jan.
its ok to be scared and you have to do what diet is best for you hun
