migraine prevention
"I had used this medication for more than 15 years, before it stopped preventing my chronic migraine headaches.  I was taking it up to 2000 mg per: night daily and didn't have any side effects of it since the very beginning of taking it (in lower dose, of course) and even when took max dose as described.



 Had a very easy adjusting to it, also and no unpleasanties whatsoever."
