migraine
"Something that really works for me when my schedule allows is to take a short nap after taking Imitrex.  I wake up with little discomfort.  My head is clear.  I can think.  One of the worst symptoms of my migraines is that I cannot stay focused on a task.  If I am unable to nap the Imitrex has little effect on me.  This is horrible when you are at work as many of you know.  "
