I blame the carbs.
Fairly standard here, I've not yet tried a brine though. I never use a recipe, just what feels good at the time. This year I made a dry rub with a bit of that Costco no-salt herb mix, added lots of sage and rosemary, some paprika and brown sugar.
I always soak the bird a few times in warm water because the inside usually still has some ice. Once limbered up, I wash with lemons and salt, then rinse and pat dry. I stuff the bird with
Then I'll stuff copious amounts of butter under the skin, olive oil the bird, rub seasoning, and stuff with quartered lemons and onions mixed with sage and rosemary.
Convection bake covered 80% of the cooking time, then uncovered with lots of basting with the drippings (oh, add about 1/2 gallon water to baking pan and replenish as needed, this becomes the gravy).
Also this year I made fresh creamed horseradish. 1 part dijon mustard, 1 part plain greek yogurt, 2 parts (by volume) finely grated horseradish, about tsp apple cider vinegar, ground black pepper, and blend smooth with a mixing wand.
