I need to study for my exams, but I'm starving - I haven't eaten all day. I'll have a quick meal and then get back to work.I can't focus on studying anymore, I've been at it for hours. I need to have a break and recharge my energy.I've been fighting off the urge to eat junk food all day, but I know it's not good for me. I'll have a healthy snack instead because I've had enough unhealthy food lately.
