I suffered from migraines for many years -from about 14 years old. I would get the 'aura' followed by a headache, very rarely debilitating tho'. I could get 2 or 3 a day and rarely had a week with out getting one. What stopped them for about 15 years was having a vasectomy. This was done to prevent unwanted children but having no migraines for 15 years was an amazing bonus!! They did start again but could mostly be attributed to sudden atmospheric pressure drops. I also found that if I took Paracetamol as soon as I got the 'aura' symptom, that this minimised the headache. If I missed taking Paracetamol at that time it became a waste of time taking them when the headache actually got going as they had no effect at all.
