Is it okay to treat myself?

I've been on a diet for two weeks and I've lost 5lb. I'm staying at my parents for a few weeks while my house is being redecorated, and my mom is such an amazing cook. She's making chicken curry tonight, which is my favourite, but I'm not sure because of my diet. I've been really good and I've gotten a lot of exercise today, so would it be okay to treat myself? x
