I've had that same issue since before I finished radiation on March 27 of this year. The thick mucus had just parked at the top of my throat. This has been the biggest obstacle to my eating recently because it blocks me from being able to swallow. In fact, today was my very first 24 hour period with no PEG food since finishing tx! (Yipee!) Like Steve, I'd swallow, but it wouldn't move. Couldn't swallow it, couldn't cough it up, couldn't swallow past it. Finally, today, I was able to go a full day without that feeling and I could eat real food. I know it's different for everybody, but for me, it seems to finally be going away. Good luck to Steve tomorrow! Truth is, it'll get worse before it gets better, but it WILL get better, and we will all be here to help both of you through as best we can.
