Hi,
Yes, nausea is definitely a symptom of anxiety. I also take xanax, and have not gotten nauseous (sp?) at all from that, but it may be different for you, so maybe you should ask your doctor to be sure. I spent several months with terrible nausea, to the point that I couldn't eat anything, but once I accepted that it was just another part of the anxiety, it did go away. You are dealing with alot of stress right now, and that may be what is affecting your stomach as well. Give your doctor a visit to be sure, but it's probably just the anxiety.
