Migraine Prevention
"I take 400 mg daily. I was having daily migraines with severe migraines each month, prior. I noticed a difference in the first week but after about 4 weeks I was having only 1-2 migraines per week and now after 3 months I&#039;m having only 1-2 per month. This has been a miracle for me. I&#039;m off all other medicines. I only take Excedrin now 1-2 times per month. I got my life back."
