It's still early. I could not eat, drink for 6 months from chemo, up to 7 weeks for my 2nd treatment post radiation, and about the same for my third treatment, and can eat everything now. Just as you can loose the ability to swallow from non use of the muscles due to losing memory, the same memory can come make use back quickly, just like any other muscle does when exercising after non use. It also matters where the primary was, where radiated, and the radiation dosage to the area, and not all are equal. The oropharynx, especially base of tongue, is integral in forming a bolus, swallowing. You also need to take care of the other issues interfering with eating, and swallowing ability..pain, ulcers, inflammation, thrush, other infections.

I had the texture thing going on just from chemo, I could not eat potatoes, bread, which would make me nauseous, for a long time.

I agree with dry swallowing, drinking, eating what you can, exercising the mouth, H&N, seeing a speech and language pathologist.

If anyone has an interest in dysphagia, iPad has a dysphagia apps that has about 10 simulation of swallowing mechanics. There is another one called, iswallow, used in conjunction with a university hospital's speech and language pathology dept, but you can view the 15 mouth, neck exercise videos. If supported by your treatmnf cancer, you can do much more in the apps.

Good luck.
