Be patient with the meds - the side effects will most likely fade off. Yes, they will; he may always be a touch slow, but the zombie dog phase will most likely pass.Thanks for checking in on us.
He is still having seizures. Mostly of the petite mal / focal variety. Almost 48 hours clear from the last.
He's now on phenobarbital, potassium bromide, and metoclopramide (for nausea). He also has valium on hand incase he doesn't come out of one.
The side effects from the meds are hitting him hard. Very drowsy. Zombie dog. Zero appetite - he's lost 5lbs since this all started. Increased thirst.
Hoping that once the seizures are under control we can reduce the med dosages to maintain him to a level where he can actually function.
Mention increased thirst to your vet.
