migraine prevention
"I have to say that the side effects are pretty harsh, but you have to remember that migraines are pretty debilitating and make life unbearable.  I'll take forgetting words rather than having 20 or more migraines a month. 
The first month of taking the med is the absolute worst, but your doctor should strongly warn you and advise you that this will happen and encourage you to work through it.  I kept remembering her words and am glad I did.  started slowly, with 25 mg in the morning, working up to 25 mg twice a day, then 50 mg at night with 25 in the morning, then up to 50 mg twice a day by the end of the month.  Never ever start bing bang boom all at once, or you won't want to continue.  Maybe for those who quit, you could try again."
