Speaking about his lifestyle changes, Shahid Kapoor said he's disciplined when it comes to sleep now. "I used to be [an]...insomniac and I flipped that after I had...kids," he added. "I've been a smoker on and off but now for...few years, I haven't smoked. I think 'Kabir Singh'...did it for me. [I was like] 'I can't. I'm done'," he said.
