cluster headaches
"I have suffered from episodic cluster headaches for almost 50 years. 25 years ago, my doctor prescribed 240mg ER verapamil twice a day as a preventative when an episode began. Excellent results...no headaches unless I drank alcohol or ate chocolate. After about 8 weeks, my episode would be over and I stopped taking the verapamil. Another episode would occur in one to two years, 30 months max. After switching primary care doctors, my new doc suggested taking 240mg slow release verapamil every day to reduce my blood pressure and maybe act as a deterrent to the clusters. It worked...it has now been four years and no recurrence of the headaches. I only hope this goes on forever. My deepest sympathy goes out to anyone who has cluster headaches."
