On July 20, I had a seizure while driving (no one was hurt, thank God) I was taken by ambulance to the hospital where I had several Tests: cat scan, eeg, ekg, urinanology, blood drawn. All tests came back normal. I believe I had the seizure due to overdosing on Xanax and hydrocone. Now I find myself calling friends and telling them about my Father's Death (8/4/13), and they're all telling me I already called them. Is this a side effect of the seizure, and if so, how long does it last. Or am I getting Alzheimers? It's pretty scary--my brain seems to be "out of wack".
