"i have only been taking celexa 20mg for about a week.  my only complaint is that it makes me extremely drowsy like a zombie and slight stomach cramps so i started taking it at night and i am considering cutting the tablet in half.  however, i have had depression for most of my adult life and like others i was against medication but i could not take it any longer.  i do feel a slight improvement i am not numb anymore but i think i need to give it more time to get the full effect."
