I also remember the changes radiation made. For me I just kept at it. I remember the same situations that you describe. I would just get frustrated & give up towards the end of a meal & feel exhausted. I have realized over time that I gulp now more than swallow & seem to belch more because of it! Oh well, whatever it takes. Swallow therapy may be in order, but for me I just keep trying. I have found that in general I eat more healthy foods; fresh fruits like melons, papaya goes down sooo smooth & no burning. Stuff like that, tomatoes too with almost everything. I don't even try to eat cold cereal at all anymore. You almost have to choose new favorite foods that you like & that are easy to swallow. Adapt & be happy. Erik
