I still can't drink beer or wine yet (10 weeks post treatment) because it still burns a little to much. I have had pizza, but right now I like it a little more without the sauce for the same reasons-the tomato and spices are still a little irritating. I had trouble with the crust too until I hit about week 8, then my mouth seemed to be producing enough saliva to get some crust down with something to drink.
Believe me, I am looking forward to beer and wine again too. It was one of the thinks that I would daydream about on the radiation table (that and food).
