migraine prevention
"My migraines are primarily abdominal, but I get daily 'tension" type headaches as well.   But my nausea "attacks" are totally debilitating and the headaches get more so every day.  I took Topamax starting at 25 mgs then increased. I noticed it really helping my symptoms, way less nausea, headaches stopped and I could sleep well.   Unfortunately, I am one of the people who react with a rare side effect of an acute onset closed angle glaucoma attack and my vision got very blurry and got so bad I could not see anything but blobs if it was more that 12 inches from my face. If you get blurred vision go to the ER and show them the letter from the Topamax website, because ER had never heard of that reaction.  I gave it a 5 because it worked until then."
