migraine prevention
"I was put on 25mg twice daily of topiramate. 

I had horrendous side effects, I managed to take this drug for 2 weeks however after the first week I had to decrease my dose to 25mg as day as I hadn't slept properly for nearly 4 days. I completely lost my appetite. I had terrible mood swings and irritability. I found it extremely difficult to concentrate and struggled remembering things. My doctors told me to persevere with this drug as I wasn't getting migraines with the 50mg dose but couldn't tolerate the side effects. After being on 25mg for a few days I woke up one morning and near enough collapsed and felt very unsteady on my feet, went to see my doctor and they took me straight off it due to a bad reaction."
