I used to go to an Osteopathic Doctor(DO). He was also a naturapathic doctor. He had me avoid certain foods and take Magnesium Cloride by Alta. You can get it at some health food stores. It always works better than any migraine Rx I ever took. I would get the migraine back even after I had taken all the migraine Rx that was allowed.
You can take 4 of Magnesium Cloride at the onset of the migraine and if it didn't go away within 15-20 minutes, you can take 4 more. When I take that, the migraine goes away.
