Tracy,
I'm glad to read that your cough is getting better. I know from experience the couging can be exhausting. I would have periods where I would cough for a hour or so. I had trouble doing all the testing, CT's, PET, and even radiation treatments. Sometimes just talking was a real job. Talking would actually bring on these coughing spells.
As for the talking to yourself. It is one of the best things that you can do. I told myself everyday that I WAS GOING TO BEAT THIS THING. Keep that postive attitude up.
Best Wishes,
Dee
