  1. Omg, I’ve only had two. The first, I thought of the “wasabi baby”, and imagined myself writing the word “help” on a piece of paper and slipping it to an emergency room physician. Googled “aneurysm” faster than you can say “shoot me”, thought I had about 60 seconds to say goodbye to everybody. At least with the second one I realized I probably would not die. Where can I score some of this drug? Be auae this pain is bullshit.

    • It is available only by prescription. You will need to find a neurologist who specializes in headache disorders to get an accurate diagnosis and treatment. Take a look at https://chsg.org/education/finding-right-doctor/ to help find one near you.
