Verapamil
"I am 29 been suffering since I was 15. I was Diagnosed with chronic cluster headaches until I was about 24. Dr currently has me on verapamil 240mg 2x daily. I've been on for approx 18 months after trying other various methods and well it Works EXCELLENT. I have 1 serious side effect..."I lost my mojo baby" no but for real being 29 and having zero sex drive and impotence problems with my current girlfriend is becoming an issue. I have tried to taper off verapamil but 2-3 days later the headaches come back. Verapamil is the only medication that has worked for me. I am not sure what I should do. Sex vs Clusters. Sad to say but I'd rather not have the headaches."
