I wouldn't like for you to set yourself up for any disappointment, but there are no right or wrong answers as far as each persons recovery time nor are there any guarantees, and reason I said, it "mainly" goes away, as far as the ropey mucus. I'm 5 years out from my first radiation, although 6 years from my first chemo, which was worse, and still have thick mucus, but it's not the ropey mucus it was right after radiation, even chemo, that needed rolls of paper towels, suctioning, medication, trial and error as far as what worked for me. Besides the time frames, there are many other factors that influence ones recovery, at least ones I know about, that may need to be looked into, some with your medical team, to help maximize.
Try to take one day at a time, each accomplishment as a giant step, at least I try to do, sometimes lol, even though at times it seems like I take a step backwards, but it does get better, and been through this many times before to know.
Good luck with everything, and keep up the good work, and posting. It probably helps more people than each of us know.
