migraine
"43 yo female migraines since 2nd grade.  Some are with aura most are without.  I get pain in my Left scapula that eventually radiates into the base of my skull through to my Left eye.  If taken right away, I get almost total relief in 20-40 minutes.  If I wait longer, it may take over an hour to work.  Works over 90 percent of the time averaging 12 headaches per month.  Side effects for me are a tightening sensation in my neck (where the arteries are on either side)  then a "floaty"  sensation.  The pain goes away and I'm left tired, yawning frequently and a little fuzzy minded, but able to function much better than with the migraine.  I've tried imitrex, zomig, midrin, and rx pain relievers.  Maxalt has worked by far the best for me."
