I got too tired (well more so) and felt ill if I didn't eat. I also had a memory like a sieve so would do the following: I made sure I made lunch the night before and wrapped it on a plate in the fridge. I also tried to pre prep any dinner for the following night I could (like cutting veg) and filled a large drink bottle and put it in the fridge to grab before a bf because I'd get so thirsty when let down happened. For snacks I had small containers of fruit pre cut and waiting in the fridge. Things like rockmelon and watermelon were perfect for this and because they were pre cut then I could just grab my container and drink while I fed.
