Thanks, everyone! I talked to my doctor again and he said since I've tried every other antidepressant available and they haven't worked satisfactorily, there was nothing to lose by trying something else entirely. I can't argue with him there. Just wish he had said that in the first place. Anyway, he's retiring and his replacement is fresh out of school. I don't have much confidence in the replacement, so I'll be looking for a new pdoc anyway. As for the lamictal, I do feel more energetic and much less sleepy overall though the positive feelings remain blunted. We'll see.
