THank you all for your responses. B eieve it or not, it went away last night when I had a can of soda. Who knew caffeine would work? And yes, I am DEFINATELY prone to migraines. My sister has them as well... gotta love that blood bond with headaches! LOL I think I will cut out the Excedrin for a while And the lack of sleep could very well be the cause. Every night, I am up until 5am and wake up at 1 the next day... only because my body has gotten immune to it. However, I did get about 10 hours of sleep today and I felt good and didn't have a headache.
