"i suffer from extreme anxiety and severe depression. i have been on cymbalta for a couple years and it makes me so tired. i couldn&#039;t take it anymore. i slept all day. i started pristiq today around noon. i have noticed a boost in energy and can&#039;t stop smiling. the only side effects so far is blurred vision, a little jittery, sweating a lot but i haven&#039;t felt happier in years from one day!"
