Sudafed will help clear your nose so you can sleep. Or, prop yourself up with extra pillows (to clear your head) until you get a response from your doctor. A humidifier might help also.
My allergies are pretty severe this time of year. I am on Alavert, Nasonex (nose spray), and Optivar (eye drops for when my eyes goo up). My doctor okayed them all, but I went without, relying on sudafed until I got her approval.
