My dad used to go to coffee twice a day, sometimes out to eat, the casino two to three times a week, but here a few weeks ago, he doesn't want to do anything anymore. He tells me he is depressed, his appetite has decreased and he says he doesn't feel hungry anymore. We have talked to his cancer doctor, and his regular physician. They don't seem to have any answers, talked to a dietician- very little help. I am trying some things she suggested. I don't know what else to do. Any suggestions?
