I have been on Vimpat for about a month now. I think I gave it a good go but I think it makes me more clumsy and shaky then usual. I am going to call the doctor tomorrow. Vimpat is the first medication that I have been on and I am not sure how they would go about changing to a new one. Do they just add a new one in or do you wean off the one you are on? Probably a really dumb question but I am concerned about it. Thanks!
