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?

Always other options.
