i am bp I but this would only be a secondary stabiliser, as i'm on lithium already and although i've destabilised it's not by much, just a wobble, and the doc is thinking of lamotrigine just to even things back up. which kind of makes sense, i think they say in the "rules" that lamotrigine should never be the primary and first use stabiliser. it can be used on its own but only after trying other stabilisers and bringing it in alongside those then dropping them.
