We're back. The upshot is, things are not perfect, but could certainly be worse.
We will address Tip's digestive issues (protein-losing enteropathy, very likely) with some diet changes, If that doesn't help, we will look into some meds (low-dose prednisone perhaps, but I'm not ready to go there yet). He has lost over five pounds.
I am to track and take notes on Tip's "episodes." My vet thinks they are currently very mild seizures, so mild and far between that he would not suggest anti-seizure meds at this point. If the episodes escalate, then we will reconsider.
Oh, and his bloodwork is all good, better than it was in May!
