My doctor suggest I take 400mg of Vitamin B2 for migraines that give me a herringbone
effect that is hard to look through. There is no pain and I dont feel nauseous. It lasts
for 10 to 15 minutes. I get this 4 or 5 times a year. MRI is negative.
Is 400mg of B2 too much? Are there side effects and does it help?
Any one with similar expierences, please help.
