migraine prevention
"I've been taking this med for almost 10 yrs now. I started when I was 18 it was the first drug my Dr tried...I am almost 28 and I am so upset looking back that I didn't ask more q's or realize that this was the issue. I started at a min dose but I was eventually up to 300mg/day. I thought nothing of this because if the Dr wasn't worried, why should I be? I had been to 3 different Dr that never asked me if at that dose I was having memory problems, etc. I don't remember anyone telling me the major side effect was memory problems, brain fog, etc no kids... I went through college thinking there was something wrong with me 
My new Dr has put me on something else that is safe if my husband and I get pregnant. She also was in shock that for migraine prevention I was taking such a big dose."
