One Man. One Goal. One Hundred Pounds to Lose.
Sorry to hear you're going through a rough patch - I totally know the feeling. Sometimes the best thing you can do is just jumpstart your efforts, throw yourself back into it and give it your all. Remember why you're doing this - that helps me regain my focus when I start to slip.
Oh_mg is right. You have had amazing results and either your head or your body is just at a speed bump. Don't worry about it. What is your specific goal for next week's weight loss? I suggest you just concentrate on next week and let the momentum take you in.
