Thanks again for the support. Yesterday her psychiatrist agreed to take her off lithium immediately. She complained that it made her clumsy, made everything including water taste bad, and, most compelling, it wasn't working, as evidenced by her latest suicide attempt. So now we're down to Lamictal and Klonopin. And last night she didn't sleep at all again. She's downstairs doing busywork projects as usual until she drops from fatigue. God help us.
