It can be so bad that you can't look at a page of print and read it, the letters look scrambled. Erik sez: Oh yes, second that. Thankfully, I've only had it that bad a few times out of the well over 100 attacks I've suffered since I developed "big M" as a child. That, plus the 'spike through the eye' feeling and the nausea make migraines totally distinct from other headaches. Erik sez: Spike through the eye? Don't you mean "skewer through the head"? ;-D I can't recall having a 'real' migraine since starting paleo. I still get headaches, sometimes with some migraine symptoms, but not the whole bag. And much much less severe. Erik sez: About the same for me, but I still have full-blown attacks occasionally. Correlation to cheating: about 90%
