i had a lot of anger and depression like problems when i was taking 3000mg of keppra daily. i also seemed to be having problems comprehending reality at times and also wide mood swings that drove me further and further into isolation. i slowly over a one year period have reduced the dose to 500mg daily and i sometimes feel like i have been reborn.
on each dose level change it took me approx four months to adjust to the new level therefore I do not rush it.
keppra, like a lot of these drugs can do wonders for some but also cause big problems for others. even worsening seizures for some.
