When Milky Way swapped the brown filling for the white, some people said it was too dang sweet. I remember discovering by happy accident that the Flyte bar* (also made by Mars) was pretty much the Milky Way of old, and would casually drop it into any vaguely confection related convo and wow people with by choc-based knowledge. Look, I'm not going to lie, a couple of times it even got me laid. People really liked the old Milky Way.
Well anyway, they discontinued it in 2015, and I've not had intercourse since.
*Weirdly, I only ever saw them for sale in Boots - whatsallthatabout?
