"i take 20 mg of celexa and 300 of welbutrin. when i don&#039;t take them, i&#039;m much more irritable. i can still feel sadness and happiness, i just feel level somehow. if you stop cold turkey, it causes nausea, for me anyways, and i can tell i feel different off them. still have some obsessive tendencies but overall, i wouldn&#039;t want to not take them."
