Why does napoleon think he is dying after he drinks the wiskey?

In George Orwell's "Animal Farm," Napoleon believes he is dying after drinking whiskey because the alcohol affects him adversely, leading him to feel unwell and disoriented. His excessive consumption of whiskey highlights his indulgent lifestyle and the corrupting nature of power. This incident reflects the broader theme of how those in power often detach from the realities of their actions, ultimately leading to their downfall.
