Nelie,
You need to get to an expert on swallowing and find out why you can't swallow. You have one? Ask another. Finding, and visualizing, that happy place where no one can swallow is not the answer. There has to be reason for this problem, and the doctor should be able to articulate it to you. I will not get into the PEG issue, you all know I had none. I had the full treatment, standard radiation, mandible resection, forearm flap reconstruction and modified neck dissection. I eat a completely normal diet. There is a swallowing disorder clinic at Yale, let me know if you want their contact information, I'll dig it up. You should only be going through this as a last resort, not as a matter of existing.
