I've been on 400 mg since mid November. I was on 400 mg last year for a most of the year, but after not being able to take the cognitive function impairments, I finally got my pdoc's ok to go down to 100 mg, which was more tolerable. This happened around August. Then in September, I went into a depressive episode, and it got so bad I was considering ECT, in November. So, my pdoc ramped up the Lamictal again, since it had worked in the past, and it was ok for a while, but now my cognitive functions are shot again. I'm so ready to just go off Lamictal, but I know that wouldn't be a good idea, b/c I'm a rapid cycler and I don't want to go through that again.
