According to the BMJ (Formally the British Medical Journal), if you read all of Ian Flemming's James Bond novels and chart Mr. Bonds drinking habits, you find that he was more of a drunk than a spy. It is an interesting read, and seems to backed by pretty good analysis, abet a little tongue in check.
From the Conclusion:
James Bond's weekly alcohol intake is over four times the advisable maximum alcohol consumption for an adult male. He is at considerable risk of developing alcoholic liver disease, cirrhosis, impotence, and other alcohol related health problems, together with being at serious risk of injury or death because of his drinking. Although we appreciate the societal pressures to consume alcohol when working with international terrorists and high stakes gamblers, we would advise Bond be referred for further assessment of his alcohol intake and reduce his intake to safe levels. We conclude that James Bond was unlikely to be able to stir his drinks, even if he would have wanted to, because of likely alcohol induced tremor.
