I'm with these guys, a big cheat of just one day will not do enough damage to your appearance for next week if you get back on the wagon and eat legally NOW.
Don't let stress turn into a massive binge - that really will undo all your hard work.
If you are stressed and don't have time for the gym some simple stretches, situps or a walk at home can give your mind a break from study and help get you back into ketosis.
Congrats and enjoy your graduation
