I used to be a singer, but never formally trained. I stopped singing for several years. When I tried to start again, every time I tried to sing, it made me cough. I believe I'd stopped singing "on top" of my breath and it was all throat. I'm doing the exercises twice a day for a half hour each. Already feeling an improvement. Camille, have you heard this particular story before, or one like it?

I haven't heard of coughing induced by singing; but if you sense breath may be an issue, I recommend starting with exercises that help balance airflow and resonance, like those below:
