I've fallen into a habit lately, perhaps I don't like the word "like," or I'm just using too many similes instead of metaphors. Is "as" okay in the place of "like," in situations like this? (excuse the unimaginative examples) He crept as a spider. Instead of He crept like a spider. The boat swayed as a man full of grog. Instead of The boat swayed like a man full of grog. Reading them now, they do seem weird. The "as" kind of looks like it's trying to set up a simultaneous action in the same sentence.
