In January 2014 the doctors were ready to put my mom on hospice, she couldn't / wouldn't eat. No appetite at all, she was down to 98 lbs and things were moving in the wrong direction. Then finally her doctor said, "I think I'm going to try Marinol" (medical marijuana, pill form). Within 2 days, my mom started eating (munchies I guess)
. Everyday that went on she ate more and more, got stronger, started to walk, pressure sores started to heal, and today 9/20/14, she is still here, 112 lbs, still on the miracle pill "Marinol". It may be worth mentioning to your dads doctor. Honestly, it SAVED my moms life. I hope it's legal in your State. I'm in NJ.
Good luck!! God Bless!!
