Lacosamide
"I am currently on 375mg Lamotrigine, and until recently, on 300mg Vimpat.  My seizures reduced from one/month to one over a three month period, but still had frequent auras. My doctor increased my Vimpat to 400mg and I have not had a seizure in over 6 months and have had maybe only one aura. My seizures have started only in my sleep and it is a relief now to go to bed with out fearing that I will have a seizure.  The only 'bad' side effect is the difficulty coming up with words. It's very irritating and does affect my job to some degree, but the tradeoff is worth it."
