Vimpat
"Vimpat severely increased my seizure activity. I took lamictal for 15 years by itself and it was extrememly effective until after childbirth.  I developed a rash after a 50mg increase to try and cover the auras I was having. So, because of "the rash", I had to stop taking lamictal altogether.  I started Vimpat before they weaned me off lamictal and I was having seizures daily, sometimes twice.  As I weaned off the lamictal, the seizures continued and then I became aggressive.  A side effect of Vimpat is mental alertness.  Caffiene is a trigger for me so it was almost as Vimpat was the equivalent of drinking several energy drinks.  I can't take Vimpat"
