Thin Within

So I have been working very hard for the last 3 weeks to get into my size 14 jeans again and I finally got back into them today!  That is such an exciting feeling when you put the smallest size pants that you have, back on.  I am going to start working very hard to get down into a size 12 now.  It may take me another month or more to get down to a size 12 but I am going to give it all i've got.  I want so badly to fit into a size 10 again but I know that I have a long ways to go until I get there. I don't understand though how I can weight the weight I way but yet fit into the size I am wearing.  I weigh 213.5 lbs and am a size 14 now.  Before my pregnancies I was a size 16 and weighed 190lbs.  I don't understand how there can be such a big difference now.  Well I will keep going and see where I can get to in the next month.
