This is a strong medicine, wears on the memory after time, not to be on for a long time, I have been on it for 5 years, my memory is getting bad and was not aware that I should not take this, other meds dont work at all, if you dont persist that the doctors find a way, they wont work for you on their own. Look into the meds they prescribe and the side effects, if I go a day or more without taking this, it will induce a seizure, like it did this last 4wks when I was sick. I need to get off this med. so I dont loose anymore of my memory.
