Hi there, is anyone on retigabine? Are you having any side effects such as number lips, bouncing head and slurry words within about 1hr from taking the medication? I have catamenial epilepsy I was diagnosed in 2008 and my seizures and still not controlled. The only happen around me ovulation and menstrual cycle and dont last very long Im fine in about 10 mins after just a bit tired. I am also on lamotrigine. Not getting anywhere with the hospital very frustrated!
