Examples
I am fussy, about my diet and straining my voice. I know, sounds a bit over the top. But I'm not as bad as I used to be. These days I don't drink alcohol for five days before a show - very dehydrating for the vocal cords, and all that acid reflux. I used to ban it for a fortnight. Nightmare.
I can't eat before I go onstage because I've learnt that burping on stage isn't a good thing. It's all about acid reflux.
