@ahernandez are you talking about totally tapering off of Keppra completely? I tapered down just 1,000 mg of Keppra (not totally off it all) with none of the effects you are talking about.
Last year at my last neurologist visit I asked about completely tapering off of all Keppra since I am doing so well. They warned me that if I was totally off all Keppra and things started flaring up again that I could not restart Keppra again. They said the Keppra would not be as effective as it was prior to quiting it completely. Go figure huh? I am presently taking 500 mg twice a day. I’m not willing to gamble quiting it totally since I know I could not return to it if needed.
