The same just happened to me with some Queen Anne chocolate covered cherries. They're absolutely rubbish, and are so sweet it makes my teeth hurt and my throat tingle. Yet, they're the candy of my childhood, and every Christmas, we had a box under the tree. I miss my family terrible fierce right now, and eating those candies made me feel a little bit closer to home.
I have a vicious tummy ache and the shakes from the sugar spike as a result. Fortunately, there's some chicken broth in the fridge. I imagine that if my appetite does return after this little episode (which it may very well do; I have a remarkable penchant for being able to eat after indulging in otherwise cloying foods) I'll sip on some broth with some sriracha and ride it out. I imagine any "hunger" I do get after this will be a sugar crash anyway, so something stabilizing will help me feel better. If I am genuinely hungry later, I'll probably nosh on some protein and fat -- anything but more sugar!
Tomorrow, I'll resume normal eating. Restricting after overeating simply sets me up for overeating again, so I'm forgiving myself and moving on.
I hope you feel better soon, too. :)
