Hey Jshect, I found Wellbutrin worked the best for me (guess I lack dopamine) for depression but finding the right dosage with other meds is tricky, too much and I'm manic too little and I'm miserable.
Right now I'm on 150mg and its been working for a while. 300mg was too much, it made me have mixed episodes and I actually felt more depressed on the higher dose.
It doesn't make sense but neither do I!
