I started Vimpat three weeks ago, was doing beautifully on it. Then My boyfriend and I were sitting in our living room last night and suddenly I past out. I felt numbness down the right arm and the right side of my face before passing out. My doctor earlier today decided that it was some type of a seizure. I also have had more severe headaches than usual. (I am a migraine suffering patient) as many of us are, right? I hope this helps any of those who are thinking of starting to take this drug, and if any of those who think we are writing to soon about it since it's new its only because wev'e already had the experience and the doctors opinion. I'm now being taken off it as we chat.
