Appetite!

Anyone else have a crazy increased appetite all of a sudden?! Today it feels like every time I finish eating I'm already starving again! I'm keeping count of how much protein I get and I'm doing great with that, I'm on my 4th 20mL bottle of water today so I feel like I should be full, but I'm not! This is the first time I've really noticed an increase in my appetite in this pregnancy and I'm 24 weeks today. Is this normal?
