Jessica,
Oh I know where you are coming from because I as well am going through the same struggle with the weight thing. I have gained weight from Prednisone it seems like anything I even looked a was an instant pound on me. I would say I was about 20 pounds over what I was comfortable with and just was unhappy with not only my swollen moon face from Prednisone but the extra weight in general so I joined Jenny Craig. I am on the 1200 cal thing too and boy is it hard cause I crave the good stuff.. Bread, chips, chocolate, fries all the comforting junk food (I feel like between that and shopping its all I have to make me feel better) sometimes I do go off track but since I joined in October I have actually lost 18 pounds soo close! I feel so much better healthwise and I really dont get much excercise because I tire pretty fast so when I can I get on my recumbent bike or I will use the wii fit or do a little walking around the mall or even my neighborhood. I guess any little bit helps.
Good Luck!
-Tracey
