"i stayed on celexa for about 6 years, as it was the ssri with the least side effects.  it worked fine for my depression, and took 6 weeks to become effective (that&#039;s about the same as i experienced with all ssris).  i ended up going off of it due to profuse sweating and elevated blood pressure (my normal is 110/70, it shot to 135/90).  diarrhea, weird dreams and constant tiredness were also problems."
