No drug should be taken before the entire list of "side effects" has been studied. I bet "decresed desire to persue happiness" is not on the list. Celexa is a problem drug. One of it's side effects is an increased desire to commit suicide. I cannot think how, with that as a risk, this drug is supposed to be considered a "cure" for depression; In fact the thought of suicide is, in itself, quite depressing. I used to sell health foods and vitamins. I have seen drugs with a "possible side effect" called "death". A better alternative is to do what many real women do--quit thinking bad thoughts, and go shopping-- a proven cure for feeling low.
