The pre-release buzz around "Dilwale" is keeping Bollywood superstar Shah Rukh Khan on his toes. He says he is `exhausted` with his hectic schedule.

Shah Rukh, who will be seen alongside actors Kajol, Varun Dhawan and Kriti Sanon in `Dilwale`, took to Twitter in the early hours of Wednesday morning to share: `Exhausted, sinused and fevered. A good night's sleep may take care of it. Only problem is not enough night left to make it good. Pill or Pillow?"

`Dilwale`, which will release on December 18, will also feature Sanjay Mishra, Boman Irani and Johnny Lever.

Apart from that, Shah Rukh also has films like `Fan` and `Raees` in his kitty which are slated to release during next year.
