To eat a meal at eleven in the evening is to insure an uncomfortable sleep. An after-dinner stroll is recommended. I sometimes work, engage in some little activity before bed. In order to achieve any significant waist reduction. Nothing deep-fried, no junk food.
Beans are a disaster.
Beer - definitely not. Describe the ecstatic trance of an extended corsetting. In the beginning of my discipline I experienced it as a euphoria and more often than I do now. Now I am only comfortable, and I am uncomfortable without the corset. It depends on their level.
