I did some looking and found some solutions she could try. Syrup being one. She had Frenchicon toast with syrup and could eat that. She said today wasn't as bad as yesterday and she ate supper. Hopefully this is something that maybe lasts a day or two in the cycle and she can eat normally at other times.

I can relate some. After my surgery three years ago I couldn't eat either. The food was the absolute worst. I was losing a lot of weight. So I started eating ice cream, salads and fruit. Turns out the food was bad because it was bad. It was heart healthy food. So once I got out of the hospital I was fine. I didn't find this out until I had to go back into the hospital a month later and they wanted me to eat and I said no and told them why. That's when they laughed and said I was on a normal menu now. That was nothing really, I could just change food. She is stuck with this.
