I'm taking my son to his doctor today to adjust his medications. He's on Zyprexa, which seemed to work fine for about 2 months, now he is delusional again. Not severe delusions like I can fly or anything, but more like he has these great plans for the future! While he sits around watching TV, smoking pot, and waiting for his friends to get out of school. He says he has these plans and not to worry about it because they are going to happen. They never do of course. He now goes from mania to depression rapidly, it never use to happen like that. I'm getting worried... Has anyone had any luck with Lithium?
