I was on Zonisamide a long time ago. What I remember from it was that I was often confused and had no appetite.

It depends on the person. Everyones different. I take it though and it works fine. Drs use it more in combination with another medication ussually

Not good for me I'm down to 109lbs. from 132 granted over a 10 year period and I already have short term memory loss from a car accident same 1 that caused my seizures to start 9yrs later
