I'm only on 2: lithium and Zyprexa.

Though, it should be noted I only started medication a few months ago and my psychiatrist says he tries to keep all his patients on less than 3/4. He says it's rare for him to give more than 2, as most of his patients are fine on one and that in America heavy medication cocktails are more common. Plus, he tries to keep it cheap so he doesn't give scripts out to the more pricey meds as a first try if there's not a really good reason to.

What I'm on works-ish, for now. I still dip in and out of depressed and manic moods but they're way more manageable now. Though, I've always been good with any medication. I rarely get even the common side effects. I'm lucky I'm not sensitive. I can see how others could need more meds or more frequent med changes due to their body. It's not 100% certain how these meds work on the brain so trial and error is going to be a ***** with this regardless.
