Romona has given you some good advice. I too went through the migraine merry-go-round. When mine started, they hit me one day out of the blue with no warning, and I thought my head would explode. That along with nausea, vomiting and nails in my eyes. I would even wake up from a sound sleep vomiting. After 2 neurologist, ultrasound, CT scan, etc, etc and a daily headache....9 months later the docs finally figured out the correct dose of meds to control mine. I usually don't get them unless I have a lot of stress.
