Your recovery is right up there in the top ten percent. As to what to expect: progress and improvement.
My recommendation would be to see a speech therapist who can give you swallowing exercises to work on eat real food again and get rid of that tube. Trust me, the longer you have a feeding tube, the more chances things will go wrong with it.
The mucous is more problematic and for many of us is a chronic condition. But maybe not for you
Glad to hear a success story
