I just started taking Lamictal but I don't have that problem. My emotions hit bottom about an hour after taking it but then that improves a short time later but by evening I am mildly manic again. I take Ativan for anxiety and it does help in the evening to curb the mania, but I always wake up in the middle of the night because everything has worn off. I hope this gets better as the dosage goes up. Except for the brief time in the morning it does help the depression.
