So I'm mainly on zyprexa/olanzapine and a pretty hefty dose of it. I'm super tired and lethargic, but I'm not psychotic/manic anymore. The long term plan is to switch over to Invega. I just had a pretty bad manic episode prior to going on zyprexa and I know it works well. Zyprexa takes away just about all my symptoms and invega works like a 6/10 but I have zero side effects from it. How long would you give it before making the switch if at all?
