Ah, I knew there was something. Thank you, Girlie.
Egg nog. BLEAH! Can't abide the stuff. (My mother used to make it from scratch and make me drink it whenever I was ill at home. With raw egg included, and I was made to watch her mixing it up. Now just looking at it is almost an emetic for me. Even thinking about it is causing my stomach to roil.)
I can't manage any meat except fish, either. That, however, is not just surrounding holiday foods--my digestion just can't tolerate them, ever. Fortunately, nobody seems to take it amiss if I fail to eat turkey (which is our family's usual Christmas fare). They're used to my foibles by now. It helps that my mother-in-law shares my food preferences; she makes smoked salmon just for the two of us when it's her turn to host. Lovely woman!
