Migraine Prevention
"Had a migraine/headache daily for months over right eye etc nothing helped.
Doctor finally gave me 40mg propanalol in twice a day (total dose 80mg) headaches completely gone. 
At first I was sleepy and about hypotensive but this was just the first three days.  Since then feel like my usual self but without this annoying headache/migraine and nausea. 10/10 - only problem is I&#039;m worried they might take me off propanalol and the headache will come back.... could I be on this indefinitely? Mmmm"
