What medications can be used as an alternative to modafinil (Provigil/Nuvigil)?

My insurance company is being a pain about covering this medication. I work third shift and rotate shifts occasionally, and I have a great deal of difficulty sleeping during the day. I got my doctor to prescribe it under the diagnosis “shift-work sleep disorder” but now my insurance won’t cover it. I’m already prescribed Adderall for ADD and was thinking about asking for some IR tablets to supplement my XR, in case the modafinil won’t be covered. Any other alternatives anyone can think of?
