I am on both Lithium and Lamictal (long story).

Lamictal has been great for me... it's cut out a lot of my rage/adrenaline racing/irritability, etc., as well as helping a little of my anxiety. It also seems to have helped with my carb cravings/keeping appetite in control.

The sad part is my P-doc tried it with me at the beginning of my dx-es, and because of the med combo I was taking along with it, it just didn't, "take." Thankfully it has now.

As Blueinanna said diff meds work different for everyone. Hope it helps you!
