Remember all.....Keppra is meant to work over a 12hr period so if you are only taking 1 pill at night, you are only protected during the evening. Awhile back, I forgot to take one of my Keppra pills and I had a seizure that night. That was awhile back and currently I have weened off the Keppra gradually and I have been seizure free for almost 3 months now. Keeping my fingers crossed.
God Bless....
