it's made me feel very hyper/somewhat manic
Yah! I guess so! LOLOL
partly because I see it as treating myself, which I don't do often, usually feel guilty if I do, and feel like I deserve very much the opposite. But oddly enough, I don't think I've ever felt guilty after chocolate-covered coffee beans.
Then I suggest you have a second "treat" lined up for yourself next time you eat chocolate covered coffee beans!

Enjoy the feeling and keep treating yourself until you get used to the feeling!
