Does anyone else wake up STARVING?

Sometimes I don't even wake myself up, it's my stomach waking me up. I can go to bed on a full stomach and still wake up like I haven't eaten in two days. I don't know if it's my diet or what but this has me confused and this if my first pregnancy so that may be why. I also get a really sickly feeling when I wake up, even if I'm still laying down I feel light headed and though I'm about to puke, but don't. That could just be morning sickness but it doesn't last long at all. Can someone help me out??
