I am sure this question has been discussed before, but for anyone with a child on Keppra only, did you notice any weight gain? My 9 year old has gained approximately 15 lbs since January and I am not sure if that is something related to the medicine that can't be helped, or if it is poor diet and lack of exercise. My husband keeps telling me not to worry but I do!! When I look at the Keppra website it says it does not contribute to weight gain.
