Hi David, you should check with your doctor because I'm not so sure you want to be taking meds like lithium and Zyprexa 'on and off'. I don't know a lot about Zyprexa (except that it makes me eat, and eat, and eat, and eat) but the efficacy of lithium depends on its serum level in your blood, so if you're only taking it sporadically you're unlikely to maintain a therapeutic blood serum level that will do you any good. Doctors prescribing lithium usually order blood tests to measure the level of lithium in your blood to make sure that you're taking enough to exert any effect on your symptoms. The bad news is, once you do reach that therapeutic serum level, you're likely to feel quite lethargic, at least for a while. It's the nature of the beast. I was once a fit and vain athlete but have put on astonishing amounts of weight after 25 years of bipolar meds that rob you of your energy and increase your appetite far past your needs. I guess that taught me something about vanity and judging others for their obesity, but I have learned to choose fat and sloth over psychosis.

My customary reminder of how Zyprexa is advertised in Denmark, "Before" and "After":
