I suffer from Clusters, with visual aura that pre-emps the main event,
they also can change my mood dramatically, my family has a long history of them, and in the old days called them 'heed nips' (im Scottish)
I seriously can become extremely right wing in my thoughts, and not very tolerant of people, this is really odd for me, as generaly I am a nice guy, with love for all.
been to the doctor, tried everything there is, in the last 20 years or so,
the one remedy that sticks is, Ibuprofen and Aspirin as soon as I get the message one is on its way, and three times a day for the next 4 days, till the pain goes away.
