Adele admits the regime made her miserable and she went back to smoking after two months, even though her voice sounded better when she was not puffing on cigarettes.
She tells Britain's Glamour magazine, "I gave up smoking for two months... It was f**king grim. I had laryngitis about a week before the album came out and it was so frightening. I stopped smoking, drinking, eating or drinking citrus, spicy foods and caffeine. It was so f**king boring. When my album went to number one here (in Britain) and in America, I just sat in my room and watched TV because I couldn't go out and talk to anyone.
"My voice was better when I wasn't smoking. Within a week I noticed it had changed, but I'd rather my voice be a bit s**t so I can have a f**king laugh."
