Welcome, neighbor. I used to live in Westerville
I know what you mean about the office foods. Currently I'm a stay-at-home-mom, but I worked an office job for about 6 years (up off of Dublin-Granville Rd.) and every year around the holidays, the office kitchen counter was full of treats. Not just from clients sending things in, but from my co-workers bringing in cookies, candy, leftovers from huge meals, things like that. So I know how hard it can be.
A few treats here and there won't hurt you, but just keep reminding yourself that all those little calories are going to add up. This is what I'm trying to tell myself right now, in fact, because I've been doing so much munching lately and holiday treats are part of it.
