Candi,
I can so totally relate. Maggie's problems were when she was lying down. It was so sad because she didn't even realize it was happening. We haven't noticed any negative side effects from the PPA, we give it to her at night before bed and she sleeps fine through the night, so it doesn't make her fidgety. The only hard part is giving it to her she doesn't like taking medicine. If it were my other lab on the other hand, she eats anything, she actually looks at me as if to say, "Can I have what Maggie's having?" I hope everything works out well with Sophie and you don't experience any side effects.
Maria
