Keep on snacking!

This whole pregnancy I've had no appetite plus food aversions but suddenly 2 days ago my hunger kicked in and I can't stop snacking. I'm not nauseous, but I get this strange feeling like if I don't snack often on starchy food I feel sort of sick. Also, I developed a metallic taste in my mouth that won't go away and it's only better when I eat ? anyone else having this?
