I used to not anything all day, then take an edible and eat all of my calories at once. Depending on stress, sometimes I regress to only being able to eat a few safe foods (when it’s really bad - only the pizza and nacho lunchables), and weed usually helps there.

Since I had stomach surgery recently and have to eat small things frequently, I bought a shit ton of bulk snacks and I always keep some with me. I also gave myself permission to buy bottled water. It’s helped a lot to have little things on hand, so I don’t have to interrupt whatever I’m doing to eat. I just grab some goldfish crackers and a water bottle out of my backpack and then I’m good to go.
