"i started taking pristiq about 5 weeks ago.  i was experiencing some nausea at first, but after about two weeks it faded.  about three weeks in i forgot to take the medicine for three days and completely plummetted into a dangerous pool of emotion.  i have been on one other medication, celexa, and what i like what pristiq is that i am still able to experience a wide range of emotions. when i was on celexa i was a little bit numb to things and wasn&#039;t able to cry, at all.  with prisiq i am more focused and i am happier."
