Nice preemptive post.
I'm basically a huge drag for the holidays so I can avoid triggers. Right now my partner is making wonderful foods replete with FODMAPs and histamine triggers, and I will try tiny bits of some of them, and savor my safe sweet potatoes and coconut golden milk while enjoying everyone else's enjoyment of the things I can't eat. If nothing else, the house smells wonderful!
We're not having anyone over, which is mostly a pandemic decision, but definitely helps with my stress level. If we were, then I know I'd be buzzing with host stress, and overstimulated by people's body product fragrances and noise and such. And definitely not eating anything someone else cooked.
I suppose in past years I have just needed a serious rest after the holidays - vegging out, safe foods, really zero expectations of myself, meditation, etc. I would take quercetin, curcumin, bromelain (as usual) and CBD to help me through it biochemically, and hit any digestive symptoms with cromolyn sodium right away. I'd also sip nettle tea throughout the days.
Another way of looking at this is that I never quite recovered from the 2015 holiday season! We hosted 40 people for Thanksgiving, at which my partner contracted coxsackie virus, and one kid there had active mycoplasma pneumoniae. Then we traveled for a Christmas extravaganza of a dozen in-laws, some of whom were heedless kids with the flu, for a sleepless week that I got through with mountains of
cookies and constant wine. When we got home, I felt worn out, spiraled downhill, and am still trying to recover! Symptoms I'd had sporadically for a couple of years at that point became constant and disabling. That's when I "got sick with Lyme," saw 39 doctors before being diagnosed, etc.
Beware the holidays, basically. I love the holidays, but it's so tempting to indulge in things we know might be deleterious, or push ourselves far too hard. Proceed with caution!
