Hello don't think I have migraines but have had a constant year and a half tension headache with dizzy and nausea .
But I once saw a national geographic TV prog , I'm not advocating drugs so see your doctor first , but this guy had been having migraines for years , he was about 60, someone told him to try magic mushrooms , so he did , and he was amazed . once the psychadelic phase wore off he said his migraine went and was able to function normaly . I think he had to take a doze every month or so.
