Feeling like a vampire

Well, I've not been feeling much like eating yesterday and today! I'm usually hungry half of the day. Why am I not when I'm usually almost always hungry that I don't feel like eating?
I've got another wisedom tooth remove!(I didn't know that I was wise, but it is okay, I guess!) And since they didn't put me stiches this time...my gum are open, and still bleeding... I have that taste of blood in my mouth(the reason why I,m not hungry!). So this how it must feel to be a vampire and feed on blood! But I want to eat real food! It's a little bit better tonigh, but still there and the gum is sensitive!
