I know about cutting salt/sugar. Anyone with a breakdown of why caffeine is bad to have? I mean obviously not right before the test. Usually I use coffee/tea to help stave off hunger pains while I'm keeping to a good diet. (IE get my carbs in the morning, so like some whole grain cereal or something with a banana/peanutbutter/almond milk smoothy, lunch tin of sardines, then dinner classically whatever because of my wife though we've been kinda playing with doing dinner separate so I can eat what I need. But tonight is steak and veggies (not potatoes)
