I eat way too much...?

Here is the situation. I eat like a small army. By that I mean, i'm 176lbs and 6ft tall, and I eat at least 3x what i should in one sitting. Example: breakfast: 3 chickens biscuits from hardeez and half gallon of OJ, Lunch: 2 footlong over roasted chicken breats from subway and a ton of water, Dinner: 16oz prime rib and 2 baked potatoes with more water....this is not to mention my pb and j snacks throughout the day. Point being, i am 20 years old and i'm frankly going broke trying to feed myself everyday. What can i do to remedy my huge freakin appetite ? My wallet and I would greatly appreciate any help.
