Hi all , my dad is at the end stages of his battle with prostate cancer he secondaries in his liver , bones and other places .He was given 2 months in April,  and then 2 weeks in August and hes still here .....He hasn't eaten any food for over five weeks , hes living off one 25ml ensure drink and water ...with the odd mouthful of coffee or ovaltine... he is wasting away in front of me ..and has lost vast amounts of weight ...he is confused and has no energy...its heartbreaking to see ...today after over 5 weeks he asked for some tomatoe soup,  he ate a tiny amount and had some mandarins blended and a can of guiness..im confused how he can go all this time with next to nothing and today has requested this .....has anybody else experienced anything like this ..i was told he wouldn't be able to digest anything after going so long without...
