I would simply put in a call to your regular Dr, ask the nurse to have the Doc call in a script for Ambien as you're taking a long flight soon. Most of the time, they'll just do it and you don't have to worry about co-pay/visit. I get my travel supplies of Ambien and Xanax this way. Note: make sure they prescribe the generic version or at least allow the pharmacist to fill generically. Once a Dr. signed the scrip "no substitution" and I wound up paying a fortune. Wonder if he got a kick-back.
