hi i just started keppra a couple of weeks ago,
the only side effect ive noticed is the tiredness
i had been warned about mood stability, cognitive performance
none of these have been an issue with me
it has basically not affected my mood at all (noticeably)
then again, i didn't even notice any side effects from dilantin
i think it's different for everybody
the good thing to know about keppra is that many people do good on it
the side effects are really mild compared to other drugs
but if you have any problems with depression, i would maybe think twice
otherwise i would give it a try and see if it works for you
