Cluster Headaches
"I am on my fifth cluster headache episode.  The last time I had one was four years ago, and they generally last about a month.  My doctor prescribed the medication to take only at night, and what a difference.  Even though I am awakened about an hour after I have been sleeping  with the cluster headache, the pain is only about a 3 - 4 on a  scale of 1 - 10.  I am up for about 5 minutes and generally fall back asleep as the pain is dull.  One night I didn&#039;t take it, and I was awakened with the cluster with pain at about a 9, and it lasted for 1 1/2 hrs.  I will never do that again.  I am very happy with this medication!"
