I was doing the same thing initially. My natural instinct was to horde supplies because I’ll definitely need then later, and just barely make it through a few fights before finally resting. I was also avoiding expending spell slots on anything that wasn’t absolutely necessary, so I could last longer before needing to rest. Then I noticed I was having issues with my carrying capacity. What am I carrying around that’s so heavy? Ah, yes, the massive buffet I’m dragging around everywhere I go. That’s when I finally accepted that there is no food shortage in the area. The game is actually a lot more enjoyable now that I can just blast out all those spells. I also learned that you can just send all of that food to camp, and when you go to the campfire to rest it’ll just pull it out of the camp storage box. No need to drag any of it around with you.
