"i have been taking 20mg every evening for about 2 months and a few days ago upped the dose to 40mg. i couldn&#039;t be happier with this medication. i had very few side effects in the beginning (frequent yawning, tiredness, lack of concentration). those all went away within 2 weeks and i was afraid they would come back with the increased dosage but they haven&#039;t. i don&#039;t feel like an emotionless zombie while taking celexa, i feel happy when i should and sad when i should, like a normal human being. it has really helped with my crying for no reason spells, as well as helping me deal with frustrations better. i wish i found out about this medication sooner."
