SO much energy!!!

I need some ideas for my 4yr old.. she has constant energy and talks non-stop. All. Day. Long. I love her to pieces but it's a lot to mentally handle. It reminds me of when kids have a sugar rush. Except she is like that every day. I'm worried about when she starts school because kids find it annoying and don't want to be around her because she's so hyper all of the time. They don't want to play with her. She is positive and fun, just need to help her learn to relax. I'm out of ideas. Any suggestions?
