Hey Callie!
First off, congratulations on your successful maintenance of 43 of your 53 lb loss. You may want to visit the "Living Maintenance" forum to talk to other maintainers, since that IS what you are.
Kudos also on catching this before it becomes a bigger than 10 lb problem.
You might also check out "Featherweights"...for those with less to lose than others.
Wherever you settle in, stick around and keep posting. Can't wait to get to know you better!
