"i have taken 4 doses of celexa thus far.  i noticed changes about 24 hours in.  prior to starting i was very out of it, sad, withdrawn, had urges to hurt myself, no appetite, nausea/vomiting, anxiety, etc.  i saw my doctor for my worsening depression and she added celexa to my other meds (wellbutrin, lamictal, geodon).  i had been on that combination and the same dosages since may 2014.  my boss noticed major negative changes since may.  today i am a little dizzy and nauseous, but otherwise, feeling much better, which is weird.  i am not used to this feeling.  i was worried this was too drastic of a change because it had been only 24 hours, but after reading other reviews, i am optimistic."
