Caffeine: Ah, caffeine. This one can go either way for a Migraineur. It can help or make a Migraine worse. For me, I find that I end up with a Migraine if I don't drink it! Note: Caffeine Guy don't even think about commenting here!
Coke Classic: The end all, be all of what I need when I feel like a truck hit me. I am not a soda drinker, but this is my all time fav!!!! It not only helps my belly feel better, but my head too!
