D is on Buspar.
He does okay (just okay) on 10 mg AM and 10 mg PM. I'll tell you though, the higher we went, the more "manic" he became. Increased hyperactivity and such. He was to the point of being on 20 mg AM and 20 mg PM and I, myself, knocked 10 mg off each time for him.
I've heard good and bad from some moms about it. As always, probably depends on the kid.
Hope it works!
