I've been taking lamictal for a while. I got up to 200 and I noticed a significant change in my moods and was a lot happier as well. I recently upped my dose and for around a week and a half I have been snappy, irritable, and overly sensitive. What is going on with me? Could it be the medicine? Or is it just a bad 2 weeks? I'm surprised by how sudden it came on too, the snappiness/irritable/etc.
