[x] Listen to the dream-lady, don't trust her
I don't think eating it by halves will cause the same effect as eating it all. Supposedly, eating a half would enhance our divinity to a certain level, and if we eat another half later (once it can not be considered the same as eating it whole), it would do nothing since we'd already have the benefits it was supposed to provide.
It is probably a poor idea to overdose on divinity with several hitchhikers in our soulspace (?), but I can't bring myself to vote against it. Half-measures are anathema to Ambition!
