migraine prevention
"This medication has been an absolute God send to me. Prior to taking low-dose Atenolol, I was getting crippling migraines once a month or so that would consume 48-72 hours of my life. My doctor began prescribing Atenolol over three years ago, and I have only had three or four migraines since - all of which I was able to stop immediately with Imitrex. I have no side effects other than sleepiness, which simply means I take it before bed and there are no issues."
