MUMBAI: Singer Sam Smith thinks his voice is at its 'best' because he's given up alcohol and cheese.

"My voice is good. (The) best it has ever felt. I'm not drinking at the moment. I'm not having dairy which is super boring. I miss cheese. I just miss cheese so much," Smith told The Sun newspaper, reports femalefirst.co.uk.

The Stay With Me singer is hoping to hold off on the booze until Christmas.

"I've made a bet with my manager that I'm not going to drink a drop of alcohol until Christmas Eve, which is really difficult," he said.

The singer says his upcoming album is set to be 'so personal', and he's nervous about releasing the record because its like 'publishing (his) diary'.

Asked why he's nervous to drop the album, he said: "Do you know what? It's because the music is so personal. And more than ever with this album and this song, it's like I'm publishing my diary. That's how it feels. It's more personal, this record, as album, than the first one."
