Hi Toots - how often are you getting them? I have both hormonal and trigger migraines. Hormonal are no problem, just more of a nuisance. Trigger migraines are a different thing altogether. My triggers are cheese, bananas and oranges in combination. Solo they are fine, any 2 together and I can have v.bad migraine for couple of days or so. It may be that one ingredient in one flavour is causing you a problem, especially as the packs deliver concentrated nutrition and there is little else in your system to dilute the effects. I find a v.strong black coffee at the onset of auras can drastically diminish effects. If you continue to suffer and want to PM me, feel free to do so.
