Have you tried any of the medications that prevent migraines? I asked my GI once and he said there were no anti-migraine meds that he knew of that could not be taken with UC. I think I was on Lialda at the time he gave me that advice. I haven't tried any of the anti-migraine medications because my doc won't treat my migraines (wants me to be treated by neurologist), but I have tried Fiorcet which was prescribed for me to take once a headache started rather than to prevent a migraine. My bottle says it causes dizziness. Fiorcet did not help me at all. The strong barbituate in it makes me nod off for short periods of time, but does nothing to relieve my pain.
Also, don't forget that migraines themselves could be causing you to throw up. You probably shouldn't take the fiorcet on an empty stomach.
I know what you mean about not knowing what to do because its a toss up sometimes which is worse, UC or migraines. I get with my cycle as well. They are the pits. I hope you get to the bottom of this and get some relief.
