The reward system is wonderful! I treated myself to a turkey platter from Germany when I lost 20 pounds of pregnancy weight. Everytime I pull that platter out for Thanksgiving, it reminds me of the discipline I once had to lose that weight.
I like the ten pound increment rewards. It puts more items into your surroundings for that reminder of every ten pounds lost. Hopefully it will foster memories to not gain the weight back too! Great Suggestion.
