Hi Gary,
I did not have a gtube because I was pregnant so I don't know if I will be any help to you. But I did not eat solid food until I was about5-6 months out. I do have some constricting but I haven't had any dilations because I don't have much of a problem with it. It has been 28 months for me and I can eat most anything except breads and meats due to lack of saliva and spicey and acidic foods.
Are you trying to eat or are you afraid to eat?
Hang in there. Things will get back to normal with a little time. I had radiation only so I was zapped of energy for 15-18 months afterwards.
Take care. Mary
