Sorry to hear about Nookie. I totally understand the freaking out bit, that's what happened to Theo back in April. Back to back seizure, so so scary.
My vet does not want to put Theo on meds until they are closer together.
However, if the time comes he did not want to start with Pheno, as it can cause liver damage as you know. He did suggest Potassium Bromide, he said he has a few patients on it and it has worked really really well. Its not toxic like the Pheno. Hope Nookie is feeling better.
