Hello.... I am on Celexa (yours is the generic brand for that) and I have been on it for 6 months now and it has been a life saver to me, my mind and my life.
I would suggest that you hang in there and give it another months before you decide to change it.... for I too was sick a lot in the beginning (like with many other meds) and then the side effect when away, plus I have found that it is best not to take this particular medicine with any of Rx meds.... for it will only make the sick feeling worse.

Good Luck....

LoVe,
