I Take Epilim For My Epilepsy (along With Keppra, Vimpat

I take Epilim for my epilepsy (along with Keppra, Vimpat and Frisium) as I have regular complext partial seizures. My nuerologist has been reducing my Epilim over time and this is day two of not having any Epilum in my system. I am having strange side effects such as non-stop crying and sadness. I don't have depression, so this is very hard. Is this just a normal reaction to Epilum withdrawal?
