RJ,
Glad to hear that you are getting back on the horse, so to speak; fighting through the first two weeks of DOMS is always tough.
I'd encourage you to more exactly determine what your caloric requirements are (perhaps using a site like
this), as guesstimation can cause problems. Weighing everything, pre-cooking most of my meals, and pre-planning my entire day's eating worked quite well for me, so I'd recommend as much of that as you can stomach. I always kept lots of sliced bell peppers, tomatoes, and other random veggies around to snack on if I got hungry, and kept very specific desserts around that I'd have on days I worked out (one Klondike bar, a single cup of ice cream, etc). It's a little bit of trial and error to find out what works for you, but it'll happen. I'd recommend targeting a minimal level of protein and then fitting the rest of your calories around that, as it's likely you're not eating enough of it.
As an aside, just to echo what others have said, it's pretty ****ty that your BF isn't being more supportive re: junk food in the home. I think your idea about segregating it to an area that you normally don't frequent is a good one, but regardless, not having that sort of thing available to eat is the easiest way not to eat it.
Good luck!
