Palpitations, Anxiety, Panic Attacks...

I have been on Nasonex for 6 months and for the last month, I have had serious anxiety and sleeplessness. I have felt disconnected at times and almost like Im going crazy. Could this be the Nasonex? Has anyone else experienced this?

I just started Nasonex and have a bad trouble sleeping, which I never did before. I can sleep maybe 3 hours but it's very shallow. Sleeplessness is not listed as a side-effect by the company, but I can't find any other factor in my life that would account for it. To make the matter worse, I don't think it's working. They say it may take up to two weeks for it to work, but I'm definitely not waiting that long without a good night's sleep.
