Been head cold / mucus / cough for over a week now and had to be out singing four nights...

Sinutab seems to stop the mucus for a while, Fisherman's Friend allows me to hear myself and avoiding deep breath songs or introducing more breathe points helps with the need to cough.

Plus the "waffle whilst tuning" can be all about the pros and cons of sucking a fisherman's friend. You'd be surprised how many actually haven't heard it.....
