Propranolol
"I have had classic migraines for 25 years. For the last 15 I have been using Inderal as a preventative. For the first 10 years it reduced the number and severity of my migraines significantly from 1 or 2, 2 day long attacks to a cluster once or twice a year. Over the last few years more frequent migraine like headaches have been developing as often as 3 or 4 a fortnight (without aura or vomiting) leading me to seek new prevention options. However, I'm fearful of discontinuing Propranolol incase the more severe classic migraines return and disrupt my work even more than the headaches do. I think every migraine sufferer who can use it should give Inderal a go. I haven't had any problems with side effects in all these years."
