You got this! It's just to throw you off, but nothing takes away from all the hard work, sweat blood and tears you put into this test. Today is just where you you can officially show you're kicking the Lsats ass.
You'd be better off drinking 2 black coffees IMHO. Red bull doesn't have that much caffeine and I'm not sure how helpful its other stimulant ingredients are. and unless you're drinking sugar-free then there could be a sugar crash
Cliff bars are my go-to break snack because they are high in sugar but have dense enough calories to stop you from getting hunry. Also, some of them have caffeine (from green tea extract).
