Sue, my husband just finished his 3rd round of the same treatment. The 1st round was the worst with fatigue, nausea and a very sore mouth. We discovered if he took a nausea pill then ate or drank calories about 20 minutes later, the nausea was minimized. Pain meds helped with the sore mouth. For nutrition I bought frozen yogurt, fresh fruit, milk and powdered protein and mixed it in my Magic Bullet. Quick and nutritious.

The 2nd & 3rd chemo had the same side effect but not nearly as much as the 1st. He generally feels pretty good in spite of the chemo. I also advanced from my Magic Bullet to the NutriBullet. See the website. It's perfect for nutrition even if he ends up with a feeding tube. I use the entire vegetable/fruit in this one. I much prefer to use the fresh stuff if possible while trying to keep the protein and calories at a max.

I also do serving-size sugar free jello and puddings with protein powder. Easy to grab and soothing on the mouth.

Hope this helps.
