yes, it's totally normal. And you won't die! I remind myself that what I am eating is PLENTY for my body. The hunger is just my body saying it wants what it's USED TO, not what it NEEDS. Your appetite will shrink, although I am comfortable with a bit of hunger, now. When you start the menu and drink your HNS's, that will help as well. Don't forget, being hungry is hard, but being fat is HARDER.
Good luck and hang in there-
