I was having nocturne seizures and when I was in my late 30s it got worse as well. I was prescribed Keppra as well and felt horrible so I was changed to lamotragin and it worked for about 10 years before having breakthrough-seizures. After failing the addition of Vimpat I was referred to Mayo for an extended eeg and they found a possible cause that I recently had surgery for. Mayo had been great to work with and I would suggest an appointment with them to see what they can do for you.
