More food, please!

I am always hungry. I thought being nauseous was bad, but being hungry all the time is worse. I know to eat 300 more calories, but when you're working for eight hrs and driving 2 hrs everyday, how do you do it? The other part that makes it bad is the fact that leftovers make me loose my appetite. So what can I premake that won't make me gag? On the upside, I'm able to eat meat again; yay!
