His career may be going great guns, but Amitabh Bachchan has had to pay for it. The Big B is suffering from exhaustion and fatigue, and his family doctors have asked him to keep away from work, for at least a month. Bachchan however is over committed, what with his film projects and television show for Star Plus claiming all his time.

The Bachchan residence has lately seen repeated visits by doctors and worried well wishers from Bollywood. Says Bachchan, `I have been been working too hard and the resulting fatigue has drained me, physically and mentally. I hardly find time for myself.`

The Big B has agreed to do films for Subhash Ghai, Sanjay Leela Bhansali, Rakesh Mehra, Mahesh Manjrekar, Sanjay Gupta, Ram Gopal Varma, David Dhawan and Mansoor Khan, and he plays a pivotal role in each of these films.Given these commitments, Bachchan says, `I can`t keep off work now, I have too much to do. I may take a break in a few months time.
