I have anxiety attacks, had for years. I currently take 1mg ativan 2x daily. The doc says try seroquel xr, so I have. first night i go to sleep fine, wake up feeling like (symptons) of sinus problems. i.e little disoriented, slightly, very slightly, dizzy, and a touch irritable. Since I have attacks and I am constantly scanning my body for issues, this caused some stress. I was wondering how long it takes for these side effects to go away, I want this to work, but I have to be able to function properly also. Anyone with some answers?
