A lot depends on the quality of your medical records -- if your current doctor is great at documentation then that and the fact that you have been on the same medications for quite a while will paint an accurate picture of your medical needs and the success of treatment.

Another factor is the new doctors thoughts/feelings about class2 medications, and the local tone of medical professionals when it comes to class2 medications. Members of the chronic pain forums that I have visited for years have remarked that certain areas of the country are horrible when it comes to the medical professionals feelings/thoughts about class2 meds... of course, in any area there wil always be at least a few good doctors, but they can be hard to find in these areas, and because they are so busy it can be hard to get an appointment.

Overall though, the most important factor is your medical records. Even a doctor who is essentailly anti-pain meds will have a hard time denying them to a patient who shows a clear need, a clear success of the treatment, and a clear history of no problems (problems such as signs of addiction).

Have you obtained copies of your medical records yet? It's important to take a look at them before you give a copy to the new doctor - just so that you can make sure that there are no errors in them and to verify that your doctor has done a good job documenting your medical conditions and clear need for treatment and clear success with treatment --- even if the records are horrible in terms of poor documentation, you can always ask your current doctor NOW to write a summary letter of your conditions, treatments, needs, success, etc... so that things go more smoothly when you go searching for a new doctor.

Another thing that might help is having your current doctor call the doctors you are going to interview with. Your doctor (with your permission) can give them a brief run-down of your history and your doctor can also ask the new doctor about his/her thoughts/feelings regarding prescribing class2 meds -- essentially, your current doctor can screen your potential doctors for you, which could save you time/energy if your doctor is able to say "this one is narcotics-shy and would never prescribe your meds" or "this one sounds great and indicates no hesitations about continuing your current treatment".

A final thought would be to go to your current pharmacy and get a copy of your complete pharmacy records. (You will have to show ID and many pharmacies also have you sign a release form).

The pharmacy records can show the new doctor what you have tried before (without having to sort through a stack of old medical records) and it can also show the doctor how long you have been on your current treatment. Plus, it's just a good idea to obtain your pharmacy records as part of your entire medical record when you move.
