My Dr That I've Had For Over 25 Yrs Has

My Dr that I've had for over 25 yrs has retired...He wrote a prescription for Marinol because of nausea from pain meds, anxiety...Now I need a Dr who will prescribe this for me...it helps so much for several of my problems. I don't have cancer and that's one reason why I've havent been able to find one. .Thank you
