My sympathies with the migraine. I HATE HATE migraine.

+1 with all those who said about the soft drink and artificial sweeteners. High Fructose corn syrup included.

Also did you change your sports drink or Goo to a different brand? I don't trust many of the sport supplements with synthetic sounding names of the ingredients and additives. My body is okay with Cliff bars, Luna bars, Fig Newtons and hate Goo, shot blocks...
