i can't eat a lot when i have to work in a hot costume for my jobs at the teams. However, if i don't eat, I get very sick. More so if I do not drink anything. I came down with heat sickness a few weeks ago at a mascot appearance and had to leave early. I can relate to how you must feel.
Hot taste foods are good too. Example (Curry)
Anyway, thank you for teaching. :)
