Hunger pangs

Ha ha it is so very normal, carry with you nuts, digestive biscuits or cookies whichever you like so that you can munch on when you feel hungry. Don't starve, then you might get acid reflex as you stated. in the due course you may develop aversions and cravings towards certain food items, accordingly you can eat and stay happy 😁 Ensure you drink plenty of water/fluids. I used to have a snacks box in our room to munch on even in the middle of the night
