Update to my own question,
Called the Fort Polk Patient advisor yesterday and explained to her that My wife and I were hitting the road to full time RV and her pain meds were going to be an issue. Like it or not those with chronic conditions such as bone deterioration will have legitimate pain that will need to be treated for the rest of their life and the nature of these medications will cause addiction. The REAL problem as I see it is not just the street addict who becomes addicted due to irresponsible use to get high but the patient who becomes addicted after a recovery from an accident or illness and while the physical pain is no longer being generated from the affected area the pain medications have taken hold and create horrible addictions causing patients to chase pills and doctor shop.
Well long story short, My wife will be seen by The good folks at Fort Polk when we arrive in late June. They say they will take good care of her and see that she receives her medications as required. They will be able to give prescriptions beyond the strict 30 day (to the day) period we have become accustomed to in the civilian world. This will allow us to continue to see the country as long as I can keep the tank full. All looks good so far!! See you guys on the road!
