Migraine Prevention
"I&#039;ve been taking Calan for over 18 years and it is truly amazing.  I was having severe, life altering migrianes at least once a week, usually twice.  The migrianes stopped instantly the week I started using this medication.  If I miss a dose, the headace will come in about two days.  Great motivation to take the medication on a timely basis.  I highly recommend this treatment for migrianes."
