I took gabapentin briefly at one point. It was not good for me at all; my moods couldn't move at all! The only thing I could feel was that unfeeling flatness.

I don't understand why you would be taking it along with Lamictal. They're both the same kind of medication, an anti-convulsant with mood stabilizing properties. Maybe you're just getting overloaded by all the medications; six is not a low number.
