Cluster Headaches
"I can make the injections last by using only 1/3 a vial per cluster attack.  I take the vial out of the auto injector and use a q-tip to press in the amount.  After this I wait exactly 9 minutes and the headache is gone.  I had a very hard time getting enough injections from my insurance to cover all the cluster headaches I was getting and this method helped me handle 3x more than I could before!  I do feel my headache pain jumping from a 3 -&gt; 10 immediately after injection.  Taking the 100mg tablets does not cause this increase in pain, but the wait is about 25-30 mins for relief.  Sometimes I can tell which headaches to use either the injection or pill for."
