Karen's dog is so cute, she should post a picture of Dharma. I have a Doberman, Morgan. She is a retired show-dog. I had her grandmother too until last November when we had to have her put to sleep. I still cry for her.
As far as the mood stablizer, Karen is correct in suggesting Abilify. Abilify is an atypical, and is a top ranked mood stabilizer. It helps with agitation, irritability, mania and depression. It usually starts helping the first day taken. It comes in multiple size tablets, 5, 10, 15, 20 and 30mg. Because the tablets can be cut in half it makes for easy titration of dose. Abilify also has a long duration of action so it doesn't hurt to be late or miss a dose. It also doesn't matter whether you have eaten before taking.
Glad your talking with us helps you.
Take care and know we support you.
