I think the lamicital is for the depressed stage and the lithium is for both depression and mania.

The lexapro (most of it) should be out of your system. Unless the anxiety/mania/agitation started near when it's supposed to kick in for depression, the mania should be gone.

I can see why Wellbutrin causes brain damage.. It's well known for causing seizures more than most stimulants and lamicital is a seizure medication.

Just thinking..

Sorry you're dealing with this stupid * hopefully it'll get better.
