My doctor only gives me enough pain medicine to last for about 1/2 month in a month! So I just have to grit my teeth and bear it and hope the Excedrin will take the edge off!! I also sometimes take Klonopin that my psychiatrist has prescribed for me to ease the anxiety that often comes with my migraines. I also have Bipolar/Anxiety disorder...what a combination, huh??
Best of luck...change your doctor if that is possible. Are you seeing a Neurologist for your migraines...that's who I go to.
