I have had exactly three of them in my life, one of which was last Thursday. I guess I am lucky because my boss gets them about 2 times a month.

They are THE most horrible thing I can think of. My eyesight goes all wacky (lights are too bright, and they flicker); my hearing goes way wacked (I can't hear what somebody is saying right in front of me, but I can hear somebody typing two rooms away); I get very sick to my stomach; and I have this pounding, pounding headache that I can feel even when I sleep. This last one lasted about 2 days, but I can still feel the effects tonight.

There is nothing worse than a migraine.
