I don't know a whole lot about nutrition, but I can tell you that the reason Coke mitigates your migranes is because the caffeine in it dilates the capillaries in your brain, which allows it to get more oxygen, decreasing the headache. Of course, caffeine is also a diuretic, so it dehydrates you. I would ask your friend/nutritionist for things that will have the same impact on your migranes as caffeine, but which don't cause dehydration, and which, of course, contain less suger. Good luck!
