Len, two years post I have just been able to handle carbonation, and I think hot/spicy things will burn my tongue for ever after amen. Doc said occasional glass of wine would do no harm, but that burns my tongue so badly that I have sworn off. My mouth did not hurt, however, after the rad/chemo sores healed. Have you asked your doc about this? I, too, was in a heck of a hurry to ditch the PEG, so can understand that.
