Hydrocodone/Medical Marijuana

I'm 62 years old. After 15 years of taking 3200mg of Ibuprofen a day for achilles tendonitis (which damaged my kidneys...before the discovery of ibuprofen's affect on them; in about the year 2000 or so), my Dr switched me to Norco (10mg Hydrocodone, 325 Tylenol...sorry can't seem to spell the generic name). Another 15 years down the road, I started having lower back, hip & knee pain. The Norco has worked wonderfully at relieving the pain. The last couple of years, I've been having trouble sleeping. Can only seem to sleep an hour or two at a time, having to get up for bathroom runs numerous times a night. California in the meantime had legalized medical marijuana. In the sense of full disclosure, I have done pot recreationally since the early '70s, but decreasingly in the last 10 years or so. Now that it's "legal", I started taking edibles as a sleep aid; have not noticed that the marijuana has had any pain relief for me, but as a sleep aid, it's been wonderful. So, Norco for pain, pot for sleep has been my regimen for about the last 15 months, and I've been feeling 25 years younger; no pain, nearly full 8 hours straight a night of sleep. I'm waking fully rested & ready to take on my days. For the first time in the years I've been taking Norco, my Dr had me do a urinalysis, results, of course, showing both the hydrocodone AND the THC in the pot. He gave me an ultimatum: one or the other, but you can't do both (due to DEA laws, etc). At this point, being a somewhat stubborn person, I'm not willing to give up my newly regained increased quality of daily life. What are my options?
