Yes, I will almost guarantee that your nausea is definitely a combo of your anxiety about taking the meds, your time of month, and overthinking this whole thing, NOT the celexa. That low a dose will not make you nauseous...please keep taking it and you will feel better all around. Also, take it every morning with breakfast...that seems to be the best time. Be consistent so your body will be used to it. I've taken different anti-deps. and none have ever made me nauseous. Good luck!
