By the spring of 1830, George's imminent end was apparent. Now largely confined to his bedchambers, having completely lost sight in one eye and describing himself "as blind as a beetle", he was forced to approve legislation with a stamp of his signature in the presence of witnesses. His weight was recorded to be . Attacks of breathlessness due to dropsy forced him to sleep upright in a chair, and doctors frequently tapped his abdomen in order to drain excess fluid. Despite his obvious decline, George was admired for clinging doggedly to life. His will to live and still-prodigious appetite astonished observers; in April 1830, the Duke of Wellington wrote the King had consumed for breakfast "a Pidgeon and Beef Steak Pye ... Three parts of a bottle of Mozelle, a Glass of Dry Champagne, two Glasses of Port a Glass of Brandy", followed by a large dose of laudanum. Writing to Maria Fitzherbert in June, the King's doctor, Sir Henry Halford, noted "His Majesty's constitution is a gigantic one, and his elasticity under the most severe pressure exceeds what I have ever witnessed in thirty-eight years' experience." Though George had been under Halford's care since the time of the Regency, the doctor's social ambitions and perceived lack of competence were strongly criticised, with "The Lancet" labelling Halford's bulletins on the King's health as "utterly and entirely destitute of information", subsequently characterising Halford's treatment of George, which involved administering both opium and laudanum as sedatives, as appearing to lack sense or direction.
