Margaret, Keep a Positive Mind, that is be big thing. There will be lots of ups and downs, more than you know. If he isn't eating and holding it down try ice cream. It works. My husband has Melanoma Cancer and he was stage # 4 and with Our Lord, Positive Mind, he has been here for 4 years and is working on his 5 years and they gave him 8 weeks to live. Our Lord makes our time and He is the only one that knows the time. If he has just started treatments sometimes it takes a while for the body to get use too it. Remember there are 7 fifferent pills out there that can help him with being sick, took Ralph work his way up to the 4th and it worked. We will keep you in our Prayers cause we know and we understand.
