Yeah this is tough for me every year...
You shouldn't have to be sick later just to make someone happy. I sit at the table but don't expect me to eat exploding biscuits, undercooked turkey and MSG-filled gravy, sorry. (Yeah, I'm pretty bitter after several bad experiences, I don't do guilt anymore...You can't guilt me into nausea and headaches.)
I'm looking forward to cooking on Friday

I am making an all natural turkey and just the basic side dishes (potatoes, stuffing). It makes up for not eating on Thursday. I always offer to host/cook but there is a lot of resistance to change so we just do our own thing on another day. Then we get good leftovers
