Migraine
"I have suffered with cluster headaches since I was in my twenties.  I am now 61 and still get them, sometimes every few months and sometimes I can go several years, but when they hit, the are debilitating and I never know how many days or weeks they will continue. My physician gave me a sample to try as I had been having these headaches almost everyday for 2 or more weeks.  Within 30-45 minutes the pressure and pain were gone and my drooping, puffy eye looked normal again.  I plan to ask my doctor if he can prescribe a larger quantity so I can take them during these lengthy episodes.  I would love to be part of a study on the efficacy of this drug on cluster headache patients.  Wish I had known about it sooner."
