"It was time to stop drinking," Richards told the Rolling Stone magazine.
"It was about a year, I took care of it, I got tired," he says.
Richards, who has also been arrested for drug possession several times in the years of fasting, says that he occasionally takes a glass of wine or beer, but that he has generally stopped drinking alcohol.
"I really do not notice a big difference, except that I do not drink," he says.
His guitarist in Rolling Stones, Ronnie Wood, says Richards is milder after dropping the drink.
"It is a pleasure to work with him, he is more open to new ideas," said Wood.
– If he goes on, I'll be there. Full support, says Wood.
