Notes from the couch

So I was reading this article tonight about the health statuses of female nurses (it was from Canada, but I have a feeling the same applies here in the states). The study listed some startling statistics about the ~2ooo nurses surveyed:

-40.1% ate less than 5 servings of fruits and veggies per day
-47.2% are physically inactive in their leisure time and
-40.3% are overweight or obese
Also, 55.8% perceived "quite a bit or extreme" amounts of work stress

I "googled" this after eating my 3rd chocolate chip cookie of the night, while sitting in my usual spot, the sunken down middle cushion of the couch. It's no surprise that in January, after most people have given up on their New Year's resolutions I find myself...re-evaluating a few things about my own life:

Like how on my nights off, I sit on this couch cushion for HOURS straight, only getting up to use the restroom or get yet another snack from the kitchen. I read random blogs, search for jobs, and watch every bad tv show and infomercial out there. I have no energy or motivation to do anything more than that. On the RARE occasion that I feel like exercising, I quickly decide that there is no easy, quiet way to do so while Emily is sleeping in the next room.
So why not exercise earlier in the day, when I wake up, or before work for example? My most legit excuse of the moment is that it's winter. At least when it's warmer out (or at the very least, when I don't have to worry about slipping on ice and snow) I can go for walks (and occasional jogs) in the neighborhood. I've tried working out before work a couple times, but that just means that my body is physically tired when I go to work, and I usually end up with sore muscles by the end of the work night. Not good. When I get home it's usually all I can do to get my coat off before I fall into bed! And honestly, most of my "days off" are nights off, and I don't wake up until about 4 pm anyway. And exercise has never been something I enjoyed--in fact I'll go so far as to say that the thought of working out adds stress to my life, which is not something I want to do to myself on my days off. Stress leads to stress eating, and I never crave celery or apples--I always want potato chips, ice cream, or cookies. So, combined with my lack of movement...I am most likely at the un-healthiest I have ever been (the only time that might have been worse was some...intense party-going days in my college years) This could totally be a picture of me every night that I'm not at work:
With multiple swim-suit wearing vacations rapidly approaching (YAY), I think it is time for a change. But this rut I'm in is really more of a crevice, not just a rut.
Any creative ideas for how to climb out???
