I am bipolar too, and my friends, that is NOT a lot of meds. Lexapro has been a godsend to me (I take 40 mg.) Lithium, not so much. I gained a lot of weight on it, tried depakote, hated it. There is a new mood stabilizer out there called lamictal (sp?) and it too, has been a godsend. As far as the neurontin goes, I don't use it, but a friend of mine who fell on the ice last year was on vicoden and it didn't work, so they switched her to that and the results were dramatic.
I know this is an addiction forum, but for a disorder such as bipolar disorder, meds are a necessary evil. Diabetics need insulin, Bipolar sufferers need mood stablilizers.
Good luck! Hope I helped.
