"i&#039;ve been taking celexa for about a month now. it helped me a little at first, now i&#039;m having crying spells and feeling hopeless again.  the glass is always half empty. i&#039;m taking 20 mg.  i was hoping celexa would work.  i had been taking paxil 20mg for about three years and i was so happy on it! it didn&#039;t matter what was going on in my life. i felt great.  i stopped taking paxil because it made me sleepy all the time.  i guess i&#039;ll continue for a few more weeks with celexa.  if things don&#039;t get better i&#039;m going back to paxil."
