...and honestly that chart scared me too until I realized the 400mg is a ceiling, not a goal. Most people don't actually drink 5 cups, they drink one giant travel mug that's technically 2 or 3 servings and they sip it over 4 hours. The trick I figured out is to split my coffee in half, so I get one real cup in the morning and then a smaller one around 1pm, and I stop after that. Also some chains use way stronger beans than others, so a 12oz at one place hits harder than a 16oz at another. If you're crashing after 2pm, try switching to half-caf or just a small green tea instead of full decaf, it's a smoother slide down.

Oh man, shredded cheese is the biggest scam out there. Once you start grating your own, you never go back. I buy the big blocks when they're on sale and just go to town with the box grater while watching TV on Sunday. The pre-shredded stuff also has that powdery coating on it to stop clumping, and it messes with how the cheese melts. It gets all grainy instead of that nice gooey stretch. Plus, you can grate a huge batch and freeze it in bags, it thaws out just fine for pizza or tacos. Your wallet and your taste buds will thank you, seriously.
