I don't know if this will help but after the surgery, the chemo was the worst part. No appetite, very tired, some nausea but not too bad. played golf every chance I could, only 9 holes, too tired to play more. Olives seemed to get my appetite going. Long walk right after chemo. I looked at it as another life experience. I attended my sons wedding and the pictures tell it all.
The only thing that I can offer is to stay positive. Don't worry about things until there is something to worry about. Then listen to the Docs. Mine were awesome. Went up to Duke cancer clinic where they did the second round of chemo and did the liver resection.
There were chemo drugs available for the second round of chemo that were not available for the first. New treatments are evolving every day. If you can hang in there long enough, something will show up that will do the trick for you.
