cluster headaches
"Was diagnosed with cluster headaches approximately 6 years ago in Canada. Took prednisone to end a couple of cycles, but decided to try verapamil. It works, but I must stress that you must stop drinking any alcohol whatsoever - NONE, don't even smell the bottle (no kidding!) Also, for me, other sure triggers include dark chocolate, white chocolate, but small quantities of milk chocolate are OK. Also, stay away from MSG (monosodium glutamate). Verapamil WILL work, but you have to stay away from triggers to give it a chance! It might take a week or two. I also had to spread it out to 3 times in a day, rather than all in one dose for it to block all headaches at first. Now I'm on 2x120mg and headache-free!"
