i have a huge 4 hour 2 part exam in 2 weeks(no rest between)
what should i eat before it to have enough energy to finish and not be too stuffed during?
Eat a good mix of protein from various sources and complex carbohydrates, and make sure to eat a substantial amount. I'm a fan of sausage/egg/english muffin sandwiches. Three of these and you'd be set!!
Caffeine is an appetite suppressor that also increases cognitive ability, so I'd have a cup or two of coffee with the meal.
I also find that the adrenaline rush caused by the testing environment can stave off hunger as you focus on the exam.
Holy shit I just had some negative nostalgia come my way.
I used to have terrible gas as a student. I'd hold it my gas in and it would gurgle up the other way back into my digestive system. It got to be as loud gurgling back up as if I'd let it out.
