Dietary swings

rosesd120211

I am 14 weeks as of today and I just wanted to see if anybody else was experiencing this too. My appetite swings back and forth so much, one second im  starving and ready to chew off a limb and the next im fine. I get this odd full feeling even if its been hours and then I get kind of queasy. So Ill make myself eat when I know its about that time even if im not necessarily hungry. I worry because before I got pregnant I wasn't a big eater so I dont really know how much to eat but im am pretty healthy unless I get a sweet and salty craving, then anything goes.
