hi everyone! I've been on Flonase for a year or so now taking it everyday.  At first month I had same anxiety problems and felt shaky and nervous most of the day.  After the second month the anxiety has gone away and my sinuses have never felt better.  I get occasional headaches from the dryness in my sinuses still.  I think that they should really put anxiety/ adrenal side-effect on the label though bc it seems like it's a common one. FDA needs to know this stuff!
