I still have a problem with anything tomato. Early on after treatment tomato juice was worse than vinegar or pickles. Avoid them for now. You likely will find is less a problem as time goes on.

Be concerned about thrush or oral fungal infections. They will make the mouth far more sensitive. I never had "typical" (ie visable) thrush symptoms but convinced the doc that I wanted to try Nystatin to see if the burning sensation would go away. Every time I had excessive burning sensation, anti-fungal (nystatin) would make it go away.
