migraine prevention
"I was given Atenolol for rapid heartbeat and high blood pressure, I was on recruiting duty and had started these problems, plus I started to have migraine headaches several times a week.  When the army doctor started treating me for the rapid heartbeat and high blood pressure, my migraines stopped. I seldom get any migraines now. I've been taking Atenolol since the mid 1980's. The Atenolol was a miracle drug for me."
