Allan, we went to his medication doctor yesterday and she said the same thing. I asked her what I can do and she said like you, you have to wait it out and just keep everyone safe. It was awful and I wanted to cry just telling her about it. She told us to get a blood draw and let's make sure his level is what it should be and if it is, then we'll do nothing for now and see if it happens again. If it does happen, she wants to add Geodon back with the Lithium. Although Geodon alone didn't seem to have any effect on him, if it were paired with his Lithium it may do the trick.
When we talked about what happened, neither of us could come up with whatever the trigger was. I had hoped that talking about it so soon afterwards with difficult child that perhaps he could tell me. Then again, maybe it was just nothing.....the nature of whatever it is that's wrong. (None of his doctors will call it Bipolar.)
