It seems that most of the time when we are having headaches and upsets during induction that the problem lies with losing so much water weight in the first few days, as well as, in many people, caffeine addition reactions. The body is trying to adjust to significant changes, and unless you are drinking enough water, and many do not, you will have weakness and headache from dehydration as well as the electrolyte imbalance.

So drink enough water, do not over exert and have some patience. It all fades away quickly.

Good Luck!
