Hi Lucas, yes it's pretty normal - some people struggle at first and others don't and how you have the packs is just a matter of taste ---- sounds like you're one of the lucky ones who's taking to it well.
The feeling hungry will soon pass once ketosis has really kicked in but the dreaming of food may continue. You might find that you dream you've ate food and you get all sad and disappointed with yourself only to wake and find it was all a dream!
Keep going strong.
