Lisa, welcome to the forums. I'm here to attest that FitDay will work if you have the commitment (and it sounds like you do).
There are lots of great people here to lend support--spend some time reading the threads and don't hesitate to join in.
There are a couple of 100+ to lose threads if you're interested and numerous weekly weigh-in threads and some challenges.
If there is anything we can do to help, don't hesitate to ask!
