Calendaring your 30 day goal

My extraordinary goal is to lose 30 pounds. My 30 day goal is to lose 5 pounds. Breaking that down into tasks for my calendar includes things like, meal planning, food preparation, scheduling exercise sessions, etc. How do I schedule things that I need to avoid to achieve my goal such as sweets and wine? I’m unclear on how the things you don’t want to do – buffering – should be worked into the calendar.
