John Mayer took to Twitter on Tuesday to commemorate one year of sobriety. "One year ago today, I decided to give drinking a break," he wrote.
"A very personal thing for everyone. For me, a constant return on investment." He added, "I post this because I want people to know that 'that's enough for now' is on the menu, so to speak."
The singer-songwriter, who turned 40 earlier this month, previously told Rolling Stone that he decided to give up drinking after deciding it was a "f**king con" and that it always went wrong for him.
