I've had Migraines all my life. As a kid I thought that everyone had the visual disturbances before they vomited - as a warning! I was 17, and a student nurse, before I knew what they were.
Anyway a doctor once told me that taking THREE Asprin AT THE AURA stage ie. before your system shuts down, is a possible solution. It works so well for me that I no longer get the headache, or the nausea. I just feel a bit seedy for the rest of the day. I can enjoy the aura and the "Alice in Wonderland" effect it gives me and the euphoria that goes with it. Joy
