Good morning @1710dave
I know from my own experience with Keppra that that is a sign on toxicity. Have you discussed the symptoms with your physician? Have they drawn a levetiracetam trough to see what your keppra level is? My Mayo Clinic physician took my off the keppra immediately when I developed similar symptoms. But it is difficult to suggest anything else because every anti seizure medication treatments are aimed at different treatments. Have you been evaluated by an epilepsy clinic?
