In terms of what they will do if you end up in a hospital, it is not necessarily that they will pump you with lithium or valproic acid. Antipsychoticd and especially Zyprexa have been shown to act more quickly than Lithium to bring one down from a manic episode, so if you end up in a hospital with mania, they are likely to go with antipsychoticd. And if you end up in a hospital with psychosis, they are even more likely to give you antipsychotics.
