Thanks, SW. I think I'll call tomorrow with an update and ask the Depakote question. difficult child 2 also has said his thoughts are still all over the place at times, although outwardly he might seem only a tiny bit agitated. When his thoughts are calm, his body seems more relaxed, too.
Good news is that the pacing has stopped, or at least substantially subsided.
I just hope the appetite issue settles down, though. He's ravenous at times.
