"This medication DID eventually help with the migraines BUT I started losing cognitive skills.  I lost my ability to process thoughts, complete sentences, was even being lost in the place I lived for 35 years.  I was very scared.  My mind was clouded all the time.  The Doctor thought I was possibly having a break down due to stress. At his same time I had been battling continual Urinary Tract Infections.  The Doctor immediately took me off of this drug and everything is coming back to normal!  I was told this is a VERY common side effect and eventually I would probably have had kidney stones also.  "
