Oh boy do I know how you feel. Before I started dating my fiance, I didn't have this problem. I lived alone and I kept those tempting foods out of my house. Now with him visiting constantly and bringing his own treats, my cupboards have change. They now have chips and pies and for goodness sakes, WHITE BREAD (he and I actually had a discussion over the lack of nutritional value in white bread)! So I have to fight my urge to dip into his food. But I just think to myself, its not worth the recourse of having to gain weight from cheating and then lose it again. I'm a loser now and I want to keep it that way. Like you I only have 20 pounds to go. We can do this, the finish line is almost there!
