i have just started taking noriday ( one week in) and i don't know weather it is the pill or not but i feel absolutly SHATTERED!!! all of the time.... to the point that i could just close my eyes and sleep in the middle of the day. I was taking off Cilest before xmas due to servere migarine. After 3 months pill free and significantly less headaches my headaches have now returned.... althought not as servere? Any advice?
