seizures
"I had been on Keppra, and Vimpat  100mg twice a day,  and it controlled my seizures well for about a year.  I then started having seizures, Then the doctors increased the dosage to 175mg twice a day, and Keppra EX 1500 mg at bed time. I became like a zombie, dizzy, fell twice and bruised my head. I attributed the symptoms, to Overdose of Vimpat at one time.  I started cutting the Vimpat pills 175mg in half, and spacing them six hours apart and now I am active,  no dizziness, no falling. So far, I have not had my hair fall out as others have reported. I called the doctors to tell him the above, but he's on vacation,  I  can't find anything on cutting the pills,  and spreading the dosage as I have done."
