I am on both Lamictal and Lexapro for temporal lobe epilepsy and anxiety. They do wonders for me but then again it's epilepsy.....I have heard of it being used for depression but I'm sure your dosage is pretty low. My dosage is 200 mg/day. That's pretty ridiculous to not have an explanation, though. I'd also be on the look out for a new pdoc. He should be open to your concerns. Hope it works out.
