I struggled with severe migraines when I was younger. I was in my forties when I had that stroke.  It was very difficult getting back to being myself again. I ended up having an eye repair surgery from a droopy lid.  
It did take many years before I was comfortable having migraines again. By that time also medication got better and I finally got a medicine that worked well with little side effects.  
My migraines when I was younger were much more severe than they are now. They would last for at least a day and the frequency was about three times a week. Now they are much more manageable, come less often, and usually last about half a day.
