A couple of things jumped out at me. First, topomax is notorious for messing up cognitive functioning.

Second, you said you were on some of these meds before. I've heard one reason not to quit meds is because frequently when you try to resume them they no longer work. I have no idea why. It's just what I've heard.

My cognitive functioning has been severely impaired over the years, I guess because I was unmedicated. It's the nature of the beast.

The only advice I have is to doctor shop until you find someone who can help you. Take care.
