I've been taking Primidone for years and years and I'm pretty much under control. I drive a car, eat well, occasionally play oldies on the radio and lead a low-key but satisfactory lifestyle. My doctor is trying to get me to switch to keppra, but after reading about all the bad side effects, I'm leaning toward staying put. Sure, I slur my speech a little and my balance isn't great but all in all I'm satisfied and afraid I'll just be worse, not better. I've asked a number of people whose opinion I value (including a RN), and they all agree with my decision to stay the course. Do you think it's wise to change horses in midstream?
