Last year I didn't have any trouble staying away from the carbs but I started trying Keto desserts. Next thing you know I was making at least one every single week. I put on a couple of pounds before I got it under control again. By Christmas I was able to have some keto dessert just that one time (in moderation like I should be able to do) and haven't had any trouble with the sweets since then.
I didn't miss the carbs at all. I made myself a cauliflower mac n cheese while others are the regular one I made for them. Just last night my husband asked why I never make that for regular dinners. He said it was really good and he hates the veg substitute stuff generally. Or at least he thinks he does because he also loved the zucchini lasagne I made once.
Halloween was what I was the most worried about because candy was my binge "food". I even made sure I had some sugar free stuff here so I wouldn't feel "deprived". I hate using that word that way. Makes me feel like a spoiled child now. Lol
Anyway, I don't even remember if I ate any of the SF stuff, but I know I handed out candy all night without a single issue resisting the sugar, and not very long ago I came across that SF candy and it was all expired and I threw away almost full packages. My T1D daughter or the other daughter that cuts carbs off and on, may have had some too and there was still stuff to throw away after several months of sitting there.

My advice to anyone that WANTS to forgo the carby stuff during the holidays is to start right now cultivating the idea that it's not food. It's simply not even a food item at all. At least not fit for human consumption anyway! Plant the seed that you're no more likely to eat those things than you would've to eat from the dog food bowl at your family dinners. Would eating the dog food kill you? No. Would it upset your stomach and make you feel unwell for a while? Probably. It's not food for you. So why would you need to try to resist eating it in the first place?
That's how I approached it and I fully embraced that way of thinking. Those traditional high carb offerings have zero affect on me. I honestly just don't want them. It's not even an effort to not eat them. It was the keto sweets that were my problem because they were allowed... and I allowed them waaaaaay too often!
Anyway, I also don't think there's anything wrong with deciding to eat "non food" stuff if you are fully aware that you may feel like crud for a while, may gain some weight back and may have some blood sugar issues if that's a condition you're working on. If you can get right back on plan and not beat yourself up and not get mad at yourself or cry about any increase on the scale, then you're probably in an emotionally healthy place with food and it will be a temporary set back.
Some things to consider going into the season though. We often think about the actual big dinners as our only "temptations" to plan for. There may be many other seasonal foods that you don't get a chance to plan for. If you decide to allow off plan eating for the these special occasions, I highly recommend deciding what your definition of special occasion is because it can be very easy to bend an already flexible rule to start allowing extra non foods in.
Does that include the very special, only baked once a year, award winning, other worldly cookies the old lady in the office brings in on some random day? Does it include an impromptu pot luck at your church? Does it include the very nice gift basket of muffins your neighbor gives you? You know what I mean.
If you do decide to allow off plan eating, make sure that it's a conscious choice of when, how often and how much you are comfortable with because if you don't set your personal limits, you may find yourself re-introducing yourself here come January with a regretful tale
