I understand that feeling completely. But you can't compare it to other weeks. The point is to take each week on its own and say "Hey there, I've lost weight! Success!"
And that's just what this week is, a huge success!
On a side note, for many people, weight loss does slow to some extent. You're a guy so it may not happen as much as the ladies, but you may find that 8 lb losses each week won't happen. (As much as I wish they would continue for you!) However, maybe next week you'll lose a bunch more! Who knows? That's in the future. For now... be satisfied that your hard work is really paying off. Besides you've lost a total of over 30 lbs! Amazing!
