Opioids to my knowledge don't work for Narcolepsy without Cataplexy. It's Narcolepsy with Cataplexy. So, if you don't have Cataplexy, I wouldn't think it would be beneficial to try them. With stimulants as with most controlled medication the best thing to do to keep them working as much as possible is to take med breaks whenever possible and switch similar medications such as Ritalin for Adderall. Tolerance is an unfortunate factor with many of these medications, and it does take work to keep it at bay.
