Newly diagnosed friend

A lifelong friend of my husband was diagnosed a month ago with cc. He had lost about 80 lbs. This did not red flag his doctors as he was overweight, diabetic and had been advised to lose a lot of weight. He had retired and had a new girlfriend so we thought this was a new start for him. Pain led to the diagnosis which is not resectable and late stage having metastasized to his liver in many areas. He has been given a stint to his duodenum and an external drain. With urging from the family they started chemo last week. He is extremely stoic about it, is on large amounts of pain meds (we think) and seems to have lost interest in anything my husband and he used to talk about. We are traveling a distance to visit him. The guys own a summer house together, have been big sports fans and bird together. My husband is at a loss as to what to say when we get there. His friend now lives with his brother and his nurse wife and they report that he sleeps most of the time. They told us to come around lunchtime and we might catch him awake. We will of course keep it short according to his energy level. My husband has no words and is very nervous about saying the wrong thing, not enough, too much etc. Do any of you who have been through this with loved ones have any ideas about this?

I also want to say that I have been following these postings for about two weeks and I am amazed at the courage and kindness of people who have been handed so much. Thank you.
