Topamax as an attempted preventative migraine medication for a month made me: tired and drowsy, cranky, have more dizzy spells, and have more nausea because of the dizzy spells. If it helped me have less acute migraine episodes I can't tell because the trade off was NOT worth it and I have still deal with the light sensitivity and weird visual aura I've had since my multi-day severe episode in March.
Started one called Divalproex this evening! Then I have a follow up in a few weeks.
