Lisinopril
"After a year of appointments & about 12 medication combinations later at the Cleveland Clinic Headache Clinic I have been on 20 mg Lisinopril, 120mg Diltiazem and 100 mg Doxepin daily for over 15 years. Down to 5 migraines per year. (Used to be 100/yr). With such a wonderful outcome we have tried to wean me off the meds 2 times. BAD IDEA. I'll probably be on these for next 30 years. But hopefully migraine free."
