What I did wrong:

• Was very afraid of saturated fats
• Ate too many peanuts
• Ate too much cheese
• Overindulged in alcoholic drinks
• Ate standing up
• Mindless eating in general (e.g., while working -- not taking a break from the computer)

What I'm (hopefully) doing right:

• Keep the Atkins book with me at all times.
• Eat real food instead of LC frankenfood.
• Keep a wee eye on calories. Not counting, but being mindful of a series of high-calorie days.
• Maintain an honest food journal.
• Commit to exercise.
