My boyfriend started lamictal for BP disorder about 4 months ago. They started him at 100mg. He has not felt right and they told him to go up to 200mg. His first night on 200 he didn't sleep well and had terrible nightmares. The next day he was agitated and hypersensitive all day. He seemed depressed and he didn't feel right.

Is he on the wrong meds or wrong dose? Or is this a side effect of going up?
