Spoiled

So I get on the scale this morning, totally expecting a gain... and to my surprise I'm down another 1.4 pounds!  This is great news and I've now lost 5% of my starting weight and I'm thrilled... however, I fear I'm becoming spoiled.  This week I ate all my daily and weekly points and actually went over my total allowed points and still managed to post a loss.  My psyche says, "If I can lose and eat more than I'm supposed to, then what's the point?"  Now understand, I'm not complaining, but I'm worried that I'll let myself slip up more often if the scale keeps saying it's okay... until it becomes the road to gaining back the 9+ pounds I've lost since the beginning of December.
