I know two people who are currently on Celexa, and I used to take it.

My dad has Generalized Anxiety Disorder (as do I) which gives us severe depression and he takes a very high dosage of it. It works miracles for him; he's credited it with saving his life and is completely different on it. My aunt takes it for depression and she also loves it. Both told me they have never had nausea as a side-effect, ever.

I tried Celexa when my GAD and depression were interfering with my life too much - at this time, I was in my emetophobia remission. It did make me feel "nauseas" and made me emetophobic again. Why I say "nauseas" is because it was changing the chemical levels in my brain, and during that adjustment period (when your anxiety can be worse), someone got norovirus around me and I totally freaked out. So, my bad experience with Celexa is all circumstantial. My anxiety manifests itself in this phobia again like it did when I was little, so it was all imagined nausea. Had that person not gotten sick, I think I would have been fine on Celexa, but I switched to Zoloft anyway and I love it. SSRI's have done great things for me.

In the end, it all depends on what works for you, as you know. Everyone reacts differently to medications. Your doctor will know best what to prescribe you. And, remember, just because a nausea side-effect is listed on the bottle does not mean you'll experience it.
