In my old age, I can do a few and that's good. It's actually not much different than how I am with most candy at this point. Post-workout Snickers every now and then hits the spot though.
I used to be able to do endless amounts in my youth. It always had a strange texture and would make my throat and teeth hurt, but I could still wolf it down like there was no tomorrow. At the end of the day, I'm pretty sure all that shit is super addictive. If you avoid it for the most part, you'll have really no craving for it but once you start eating it at all frequently, it's a hard habit to kick as gross as it may seem when you're not in it.
