Hi, I too suffer from sinus problems. I don't get the runny blocked nose, but I do get a very full feeling in the head. I can't stand it. I also dwell on the anxiety a lot during the day, which just makes it all worse. I get dizzy when I drive, I feel like things are moving that aren't, and that things are swaying. I notice also that I stare a lot into space and get dizzy from that. I have had anxiety for 6 years. Along with a bitter childhood, and abusive relationships, I think it was a concoction of terror waiting to happen. :) I was taking serzone up until a few weeks back.. had been on it for 6 years. Decided that was too long to be on the same medication. If anyone else has been on that, or has dizzy and feelings and of swaying.. email me marmalade75@hotmail.com
