Seizures
"First I had partial seizures (after head injury in 2004) and after grand mal 2014 I almost died because of status epilepticus. After that I am on Keppra 1000mg a day (500mg morning, 500mg evening) for 2 years now. First month or two I had headache and double vision, sometimes I was a bit aggressive 
but after few months it was ok. For me it is good medicine, now i have 10 petit mals a year and I think that bad-heavy weather changes is causing them. 
I want to tell you, that after first or second month side effects went away. For me it is important, that I take Keppra with good meal in morning and evening. It is good medicine, just do not give up. 
Love you all."
