"He was seldom out of his bed before noon, when he drank a cup of very strong green tea, without sugar or milk. At two he ate a biscuit and drank soda-water. At three he mounted his horse and sauntered along the road—and generally the same road,—if alone, racking his brains for fitting matter and rhymes for the coming poem; he dined at seven, as frugally as anchorites are said in story-books to have done; at nine he visited the family of [his teenage mistress, Teresa Guiccioli]; on his return home he sat reading or composing until two or three o’clock in the morning, and then to bed, often feverish, restless, and exhausted—to dream, as he said, more than to sleep."
