I was on topamax for 6 months. I became so stupid....When I talked to my neurologist about it, he said "Why do you think they call it dopamax"? I couldn't concentrate at work. I saw my work slipping, I couldn't keep details straight. I just took a leave of absense to get off the meds cause I was so messed up at work and embarrised.
Oh yeah the topamax never helped my headaches either.
