My daughter has had migrains since teenage years.  In her 20's she worked with older lady who told her to take 3000mg of b12 a day.  she does not have them anymore and swears by it.

I also had terrible migraines, but after I had been diagnosed with hypothyreosis, I started taking therapy and the mirracle happened - the migraines are now gone.

Can't explain it, I also asked the doctor here, I think his nick is migrainesurgery, he said something that it was interesting and  this field should still be researched.

When I had migraines, I was on wet cloth, complete darkness and minimum 2 painkillers.
