Migraine
"I have read many of the other reviews of Sumavel DosePro and agree that I have had some not fire when I go to inject myself.  I have learned to be patient and continue to hold the applicator in place and continually push it into my skin until the injector fires.  It sometimes takes a while, but it does eventually goes off.  You just need to be patient.  Yes, it&#039;s frustrating, but when you have a migraine, it&#039;s worth the wait.  This has been a miracle drug for me and I will continue to use it as long as it is available to me!"
