This makes me wonder if OP skipped breakfast or something, because while skipping a meal isn't a pleasant experience, you shouldn't be so starved that you resort to antacid tablets. I'm inclined to think that OP is just a little weak-willed, because for most people, missing a meal won't hurt anything. In fact, it can do more good than harm if you do it in a controlled fashion (not compulsively from a mental disorder); many people, including myself, will intermittently fast. I'm sorry that OP forgot their lunch, but the human body is easily capable of going on without food for a few extra hours... suck it up next time, don't go eating out of the medicine cabinet just because you're not used to being really hungry.

Could also have an undiagnosed medical condition like diabetes or pregnancy. If I go too long on an empty stomach I get extremely nauseous (sometimes to the point of heaving). Pregnancy makes the amount of time ridiculously short (approx 2hrs). Eating too soon after waking also = nauseous.

"undiagnosed medical condition like... Pregnancy" just made me laugh

Yeah I hate skipping lunch but I've done it before without eating breakfast either

Pretty sure if I missed lunch I wouldn't be able to function. Not everyone is able to skip meals easily.

I'm guessing it was to stop their stomach rumbling.

I agree. Though maybe op can't afford it? I work full time and I can barely afford eating out more than a few times a month.

They could have also asked a co-worker for some money, right? I am sure they would have understood the situation and as long as they were paid back everything should have been alright.

ydi. you couldn't go to the store our something and get lunch?
