Hello again. I am sorry that you are still struggling with your insomnia. The ER will most likely not be able to prescribe you a Controlled Subdtance like Ambien, but they can prescribe you a Non Controlled Substance like Trazodone or Seroquel at a low dose to help you sleep. You can also show the prescription for Restoril as proof that you are being treated for insomnia.
Also I will not be able to provide a phone call at this time due to the late hour.
