I have never had any grandiose thought at least not the types I have read about. I could not tolerate lithium and lamictal did not work for me. I am on seroquel but that does not control my mood swing i have horrible insomnia so it is more for that. Seroquel does suck in the fact that the urge for sweets is very strong. if i cheat at all i gain weight i gained 3 pounds over the few days around christmas. i have to watch everything that goes in my mouth. i keep it under 1600 calories i should be losing weight but that does not happen. I am currently trying tegretol which is an anti seizure medication like lamictal but is supposed to be better and moodiness similar to lithium.
