At prescription amounts, yes it pretty much turns the patient into a robot. My stepfather is bipolar, and his doctor had to stop prescribing him lithium because it stripped away his normally upbeat (when not in a depressive state) personality, to the point that he was difficult to interact with.
Again though, that's at prescription levels. Trace levels in drinking water probably won't make us all into soulless robots ripe for totalitarian rule.
