Yep! I've been keeping a migraine diary since 1998. For twenty years I averaged 12-15 migraines a month, where I define a "recordable" migraine as one that stops me from doing anything other than taking care of the migraine for more than an hour.

In 2018 I started Aimovig (later switching to Emgality). I now average between 0 and 1 migraine a month.
