The attacks of nervous irritation increased. One moment Hitler’s collar was too tight and was stopping his circulation; the next his trousers were too long. He complained that his skin itched. He suspected poison everywhere, in the lavatory cistern, on the soap, in the shaving cream or in the toothpaste, and demanded that these be minutely analysed. The water used for cooking his food had to be investigated as well. Hitler chewed his fingernails and scratched his ears and neck until they bled. Because he suffered from insomnia, he took every possible sleeping pill. His bed was warmed with electric blankets and cushions.
