Lithium muted me too... Nice and quiet at first, but my muted personality soon had me ripping out my hair, ugh,not to mention the shakes! They say tremors are a side-effect, I dont consider not being able to butter bread without messing, a tremor! Yuck, got rid of that s.h.i.t! No experience with seroquel, but it made my sister fit into her pregnancy pants and resurrected her teenage acne too... Hope you have better luck than we did
