What Is Causing Depression And Nervousness?

My wife is using Olanzapine (2.5MG) along with 30 MG of Paxel before bed time. She is very hyper part of the day, and tired. She can t sit still, read, socialize because of her nervousness. She was fine for over a year taking 30 MG of Paxel. However, she received her doctor s approval to cut the 30 MG down to 5 MG. The same doctor has just upped her dose to 30MG with Olanzapine each nite. She was fine with 30 MGs, so I don t know why he went along with her to cut it down to 5. She is still Depressed, He took her back up to 30MG two weeks ago, along with Olanzapine. He was not the same doctor who put her on the road to recovery with the 30 MG dose over a year ago. We have an appointment to see the Doctor who was responsible for making her well with the 30 MG dose. We had to make the appointment 3 wks ago with him, as over a year time expired, so she was considered a new patient.
