wannabbetter, your symptoms of tiredness sound just like mine. Several days, two days or even the day before a migraine, I will feel exhausted for no reason. It takes effort just to walk around - an exhaustion like none I have ever felt. I never related the two things until just a few months ago. I actually posted on here asking if anyone else had this and wondered if this would be considered an "aura". I never get the flashing lights, etc. but can say that now I notice the exhaustion and know that a migraine is coming. Now, when I feel that tiredness, I will start all of my abortive meds. All of this usually happens in conjunction with weather changes, also.
