had awful migranes when I was pregnant and would not take pain killers for it; felt like someone was drilling into my head. I am short sighted and get vision disturbances, so its good to know there are others out there with this issue. I have been taking Ibuprofen with lyesine that numbs the pain quite well now.. When I was pregnant I also bought a product called "4head" which i still occassionally use. By the way what are cluster headaches?
