I had some boneless wings for dinner and they were delicious!! I feel sick as hell now though... I'm noticing what makes me feel sick is mainly this nasty film covering of grossness on the back of my tongue/throat. It tastes awful and I can't brush that far back to get rid of it! I tried mouthwash, salt water... Anyone else have the same issue?
