Migraine...holy moly!

I usually get one migraine a year if that, pretty mild, but today I had a doozy. My vision started going on the sides and spots and flashes, then a pounding headache on the right temple with major sensitivity to light and sound. I was out for 3 hours- no lunch- after taking tylenol and woke up dehydrated, weak and still with a major headache. My husband was an angel and brought me G2 and takeout teriyaki dinner for the family so I wouldn't have to worry. I'm wondering if I could be getting migraines because of the extra hormones in my body as I'm losing weight? Has anyone else experienced migraines when they didn't before or increased migraines after sleeve? Sleeved July 2nd.
