doesn't work for everyone - but it was working for me! we experimented with lots of preventative medication til we found one that worked - when it was working, we went and tried a generic drug that was exactly the same except it had no caffeine - i got migraines again. so we experimented with the coke, and it was working really well. i've managed to go 10 weeks relatively caffeine free (have had maybe half dozen cups of tea and one glass of coke!) but have now been suffering for days with a headache - which makes the morning sickness queasies sooooooooo much worse!

it was definitely a weird experiment (but i've heard it from a number of people now so can't be THAT odd), and one that worked and saved my parents (and i guess me now) heaps on preventative and treatment meds!
