migraine
"I have migraines usually 3 to 5 times a week and my neurologist gave me this medicine. I am also taking propranolol and have not noted any side effects. I have found that for me it works best when taken at first signs of a migraine. If I take it when I already have a migraine it doesn't work. There is a little nausea afterward but a little food helps. It's a very effective treatment and no rebound headaches."
