Kit Harington ditched alcohol before he checked into rehab as he noticed he was struggling with stress.
A source told the New York Post's Page Six column: "It's such a long week, with rehearsals and filming that can go on until 3 am. But Kit kept his wits about him and we noticed he didn't touch a drop of alcohol - even at the after party. "
The 32-year-old actor checked into the facility to work on some "personal issues".
His representative said at the time: "Kit has decided to utilise this break in his schedule as an opportunity to spend some time at a wellness retreat to work on some personal issues."
