I have both. I'm on 1500mg of lithium, 60mg of Cymbalta, 15mg of Zyprexa, 25mg Seroquel PRN, and 10mg of Ritalin. The Ritalin worked at first but I quickly became used to it and I doubt my pdoc would up the dose. Pdocs are very hesitant about prescribing stimulants for bipolar patients since they can make you manic. We've been working on getting the right cocktail for awhile. I love the lithium as a mood stabilizer but I would recommend Zyprexa only in acute situations or as a last resort. I gained 35 pounds in a very short amount of time during back-to-back hospital stays.

I think you should ask your pdoc to adjust your dosage for both meds. You can ask what the other options are besides Latuda, but just know you'll probably have to deal with side effects if you switch.
