seizures
"I am 37 years old and have had Petit Mal Seizures since I was 2 Years old. My seizures were always controlled on Epival. However, this drug isn't safe during pregnancy so my Dr prescribed me Keppra (500mg) before we staring to try for a baby. 

Keppra works well for me to control the Petit Mal Seizures. However, it has really bad side effects. It made me extremely tired and quite moody. The worse part about this medication it caused me to have 2 Grand Mal Seizures (10w and 18 w). Before these 2 seizures I have never had a Grand Mal before.  I am now off of Keppra and on Lamotrigine and feel great. I have energy and feel like myself again. Best of all no Grand Mal seizures!"
