Snacking just to snack..

I'm having a major problem with this. I came back to my parent's house for the holidays for about two weeks, leaving behind my super healthy food selections and my ability to run outside or go to a gym (well, I could freeze and run outside in the 20 degree weather). I've been doing indoor workouts, hour long intense zumba sessions/interval cardio and such. This is a far cry from my 4 mile bike/walk a day and 45 minute workout that I would do everyday.

I also am taking a break from work, and I find myself not busy and besides the shopping, I am sitting around the house a lot and am tempted by all of the Christmas goodies and just normal things that I don't normally have in my house because they're dangerous to me. I can turn anything into a binge food, honey nut cheerios, granola bars, etc. They have healthy options but I've just had them for so long that it's nice to eat new things (even though I should be eating low carb/low glycemic for PCOS).

I'm trying to enjoy the time with my family and enjoy the Christmas parties, but I find they stress me out because I eat too much during the day! Totally mindlessly and without reason a lot of the time. I know I'm doing it, I ask myself if I'm hungry, which is usually no. I don't eat it then but I'll go back 5 minutes later for it.

There's no scale so I don't know if I gained, but some of my pants do feel tighter (could be temporary bloat). I know that I'll be back to normal in a week or so, but that doesn't mean I should give up completely, does it? Does anyone have any advice?
