My overnight bag has a snack shelf and a refill calendar

I do 3 nights away every other month for work. At home my usual is protein shake at 7, lunch at 12:30, dinner by 6:45, and a 20-minute walk after lunch. On the road my steps drop to about 4k, and restaurant sodium adds 2–3 lb of water by day two. What helps: I pack 5 shelf-stable protein shakes, 2 apples, a collapsible bowl, and a 1-cup measuring cup. I pre-log breakfast and one snack. I also set a calendar reminder 5 days before my refill window, because last trip I came home to an empty fridge and a 4-day shipping delay. Comparing home vs travel weeks: grocery spend goes from $62 to $95, but takeout goes from $18 to $70. My system is boring: same breakfast, same walk, same water bottle refilled 4x. I don't try to match home calories exactly; I aim for same meal timing and protein at breakfast. What do you pack or schedule that keeps the week from turning into a free-for-all?
