Hey Betty,
As a caregiver, I know what you are going thru. I think she needs to know that it's just so different for everyone. For my Dan, radiation was quite hard, chemo not so hard. The anti-nausea drugs given before each chemo helped a lot. Dan took nutrition from a PEG tube for about 5 months. He has been slowing eating for the last month...very little at first and better now. He just had his PEG removed yesterday and is doing well. As Dan Bogan and many others say...tell her to measure progress in weeks...definitely not days. That really helped us thru. Sounds like she is fortunate to have a good support system thru you and other family members. We had a bible study support group that was definitely from God and so well received and helpful for us. You are in my prayers!!
Debbie
