migraine prevention
"My doctor prescribed propranolol explaining how he'd like to try to prevent the migraine in the first place, rather than treating it after it arrived.  I explained I'd prefer that as well.  Propranolol was prescribed, 1 tablet twice daily.  

After trying the 60 mg. tablets for three months, I reported only having 6 migraines  during that time period.  He thereby increased the strength to 80 mg. and I currently experience an average of 2 migraines a year!  And it's so inexpensive!"
