"i feel so much better since i started taking celexa 2 weeks ago, i am 41 and was feeling very negative and tired all the time and sad. i didn&#039;t want to interact with people. now i feel like i did 15 years ago, it&#039;s great, more energy, i sleep less and i am doing more things socially, already.  a few side effects were headache and eye pain but they have almost completely gone away and i am so glad i stuck with it."
