Yes I had a similar experience. Somewhere after reaching lv 3 and after fighting the goblin attack outside the druid grove, the harpies and the owlbear I needed a long rest because I was all out of spell slots on Shadowheart and Gale. The party was almost full on HP at that point, but I wanted to be ready for a tough right if I happened to stumble into one. (Also I didnt even know food = healing I just used a potion every now and then.) XD
