Which one would you choose?

I'm on 400 mg of lamictal, and it's really messing with my cognitive functions, but I'm more stable now than I have been in more than a year. It's really messing with my memory too, and I'm having word finding issues. I feel so dumb at times. Like last week I had a phone interview and could barely get out what I wanted to say, and forgot over half the stuff I did at my last job.

I just don't know how much more of this I can take.
