Welcome to OCF. Im so sorry to read of this sad situation. For more protein, pick up some high protein powder at a drug store or grocery store. Even Walmart sells it. The formula he is on is complete nutrition, kinda like baby formula. Im assuming it is used with a pump.

Recovery can take a while. Have patience and in a few weeks he will begin to feel a little better. Oral cancer is a rough one to get thru, its very different than other cancers. Oral cancer has its own set of side effects. I read about your aunt going thru radiation for cancer in her lungs and brain. Im sorry for your loss.

Best wishes for continued improvements for your FIL.
