Starving for Dinner

I don't know why but I've been getting really hungry nowadays. I got home around 7+ last night after battling traffic and was starving! Luckily mom had cooked dinner and I couldn't wait to tuck in! Weird thing was I ate lots but still felt a bit empty. Then later last night, I ended up with a stomachache :( Maybe I was having a bit of gastric due to my light lunch.
