Are you still seeing the same group of docs who did three surgeries? Because you sill take lots of meds and still have seizures, a change is in order. Fast. Would scare me to be with the same ones. There are many talentes/experienced epileptologists out there who can offer a second opinion and might offer you a better quality of life that more pills and headaches. Consider a second opinion with your PCP doing the referraL. Surgery is supposed to stop the szeizures. I wish you the best.
P.S. My doc, after my switch to keppra, wanted to up me to 3,000mg a day. I wanted less and did not go for the higher dose. I was fine on that, and now down to half. More is not better in all cases, especially after surgey. Tattoo
