That's awesome, congrats! I think having pants get that loose has got to be one of the most rewarding feelings (that sounds a bit weird, but I think you know what I mean). You definitely deserve a treat, keep up the great work!
so i went to gabreil brother's, and I got 2 pairs of lane bryant jeans ($5 each) one for the size i am now, and one one size down. however, i made the mistake of bringing my husband, who rushed me to the point of it not being fun any more. oh well! New jeans woot!
