There is no "right answer" for this, as it is difficult to predict how certain people will respond to different antidepressants. However, your depression seems to be returning - so Pristiq is not a good option for you. A recent study has shown that Lexapro and Zoloft are the two most effective meds for dpression, and I have found that my patients has less libido diffiulties with lexapro. You may want to give this a try, but nobody (including me) can say with certainty that it will be any better than the celexa.
Good luck and please click ACCEPT if this information was helpful. Thanks.
