Topamax and restroom

I have had migraines for several years now and just recently found out that the med I was taking at each episode was really for those that have migraines a couple of times a year - I have them a couple of times a month. I was prescribed 50mg of Topamax, two times a day. I took both doses on a Thursday and could not go to work on Friday. By Thursday night I was lightheaded...by Friday morning I couldn't keep my eyes open, my brain couldn't seem to tell my fingers how to type, I couldn't come up with what I wanted to say, I tried to read in bed and couldn't even concentrate on what the book was saying. Normal events (taking my 2yo to the restroom, walking into a restaurant) were exhausting. I'm going back to the doctor tomorrow to discuss all that occurred. After reading all the side effects online, I would honestly rather deal with the migraines. At least I know they will go away. With the Topamax I felt completely out of control of my body...never a good feeling.
