The kids safety is #1, but I'm wondering if the medication your wife is taking is adequate!! I'm wondering if she needs something else or should be seeing a therapist. This medication might not be what she needs at ALL. She doesn't sound depressed AT ALL and that is what Prozac is for!! Was she depressed BEFORE she went on Prozac??? If she was, it's certainly having an adverse affect on her.
Talk to her doctor and tell him/her what's going on! Something isn't right. Prozac does NOT sound like the right medication for her. Someone dropped the ball with this woman. She's acting like a crazy person. Is this how she acted BEFORE the medication? It's important to know that. It COULD be the medications' fault. Did she act like this BEFORE medication?
