I'm only on 150 mg of Lamictal. I haven't noticed any slowing like you describe. I'm definitely not emotionally numb, because my boss made me cry for 15 minutes yesterday ;-). For a long time, once I got up to a decent dosage, I felt pretty good -- even, at least, not up half the day and down half the day. I'm back to that now, but there are reasons for it, so I'm chalking it up to stress, not meds.
