yeah, just get moving. or cut out soda or something. you don't need to do anything crazy or drastic to kick-start your weight-loss. if setting up difficult challenges was too hard for you, start with small ones.
i've also been on-an-off on this site for about 2 years, and now i'm back again and trying again, and baby steps is the way to go. and i might fall off again, but even if i do, i'm still gonna give it my best for now.
good luck.
