Hi Teresa!
It sounds like you have a really good mindset, which is so important! And we do have successful losers here who also quit smoking, so don't let that stop you! Just get lots and lots of sugar free gum.
Anyway, we have forums by eating plan, which may help you make a decision on your plan...look at the calorie counters, South Beach, and more to get an idea of what's out there. We also have a 40-somethings forum, for those in your age range.
Happy new year, and congrats on heading toward a Happy New You! I can't wait to get to know you better, so jump in and keep posting.
