I had a seizure 9 days ago due to benzodiazapine withdrawal (which was my own fault, I just stopped taking my meds). I'm back on the Xanax and have had no further seizures but I'm still having short term memory problems. Is that normal? It's starting to worry me. Apparently the seizure was pretty bad, I was told I was convulsing and foaming at the mouth for approx 5 minutes. Do you think some kind of permanent damage was caused?
