Topiramate
"I've been on this medication for a few months.  Prescribed by neurologist for my chronic migraines.  I tapered on slowly and now take 50mg am and pm.  I usually got at least a few migraines a month..with aura.  I've had them my whole life.  Some worse than others, some so bad I could've gone to the hospital.  Since I've been on the meds I have not had one migraine with aura.  Just a few headaches could maybe be considered very mild migraines.  A huge improvement.  I've also lost 25lbs.  I have noticed I've been a little forgetful and have had some brain farts at work.  The medication has given me really bad acid reflux that I'm still struggling with and it's apparently pretty rare.  Otherwise it's been ok for me."
