Sorry to hear about your long night... Glad to hear Maple is feeling better this morning. I wouldn't worry too too much just yet... Puppy's puke... at least mine has a couple times. Usually something she ate just didn't agree with her stomach, and one time she threw up because she swallowed a couple small pieces of her chewy nylabone. I am sure she will be fine especially since you said she seemed normal this morning and was hungry as usual, that's a very good sign. Make sure she drinks plenty of water, and just keep an eye on her.
