You know yourself well enough not to eat a tacobell 4th meal, then wake up to mcdonalds and starbucks for breakfast before your 8am test.
Eh. I had to travel a long way for my MCAT and lived for about four days on what I brought in my cooler, and (lots of ) fast food.
I didn't have a stroke or fall asleep or pee myself during the test or anything. As usual, I think SDN is way, way, way overblowing the importance of MCAT-centric food.
The big thing is just to make sure your blood sugar stays level, and that you find something palatable enough to actually get calories in the day before. McDonald's cheeseburgers did it for me.
Seriously. Just...eat food. Not something ridiculous, and stay on top of your calorie counts since you'll be so anxious that your appetite probably won't work right. I've found stonefruit is good for nervous tummies, as is any aromatic fruit, really. I destroyed some lychees during my terminal studying. God those things are awesome.
I will however shamelessly plug those
awesome cheddar cracker with peanut butter things. Nicely calorie dense, and also delicious as ****. If you're like me and never get hungry when you're nervous, they're also easy to shove into your mouth wholesale and force down with some water.
That's what I did between verbal and the essays. It didn't make me feel like superman...but once again, no strokes or psychotic breaks or anything just because I didn't pasta-carb-load for a week beforehand.
