That sounds terrible. I had bad side effects with high doses of depakote, lithium and akithesia (THE worst side effect I've had) with haldol, loxitane, stelazine.

The anti-psychotics (ie Seroquel) are also labelled as "mood stabilizers" along with lithium, depakote, lamictal (also an anti-convulsant).

Hope you get some better advice. Neurontin is not used by Psychiatrists for manic-depression nowadays (nor was it ever very popular among Psychiatrists). First line of defense has always been depakote or lithium then add other meds for anxiety, agitation, psychosis, etc. (You can find BP treatment flow charts in literature and maybe online which are used for training purposes.)
