migraine prevention
"I suffered from Migraines with increasing frequency from about 6 years old. When I was about 14 I started to get them four or five times a month. At 15 I had a constant Migraine; I would black out and faint every time I stood up, I couldn't sleep or eat. At points I just wanted to die. It never went away and a long list of pain killers and other medications failed to work. Propranolol stops them almost completely. I still get them every couple of months, but that is not so much of a problem."
