I also have headaches almost daily. Two of them are migraines. I usually take Excedrin or Fironal. Just went to a neurologist two weeks ago. He thinks I am having rebound headaches with the Excedrin. He cut me down to two a day of the Fiorinal. He told me not to take the Excedrin so often. I'm doing what he said but still having the headaches,. I've had two migraines this week. It's hard to just take the 2 pills. I'm used to taking three. He cut me down since he thought the frequency of the migraines could also be rebound. I had Botox injections this week. He said it will take 2-3 weeks to see any difference.
