Whats the difference between maple syrup and natural honey?

I have a huge problem. I sent my mom out to buy me some Maple Syrup while I was at school and instead she brings home 100% pure Natural Honey and worst part was that she opened the 15lb. bottle to "taste" it and now I can't take it back for my money-back since it's open. I don't know if it's okay to finish the diet with the natural honey, or I should go buy the maple syrup. So far I've spent $40 bucks on the diet cause syrup and lemon over here is so expensive. I'm just 3 days away from finishing and I really don't have more money to spend and I don't know if it's okay to use the natural honey. Anybody have an answer to this, please reply. Thank-you.
