Four weeks out from radiation and my wife thinks i should be getting off fentnayl patch. Its only 25 mgs. cuts the pain in my tongue i think. the pain isn't that bad but she feels if i get off the drugs my appetite might start. any feelings on this. the only other drugs i take are percocet lowest dose. I take that at night before bed as my tongue usually hurts a bit more. then i take adavan .5 mg as needed. about three times a day I feel they are all low doses and should keep them for now. maybe another month. any imput
