You and Diet Dr Pepper go together like peanut butter and jelly. You can’t get through your 4 p.m. meeting without a Mountain Dew. Watching a movie in the theater is unbearable without an ice-cold Cherry Coke.

But it’s time to face the facts: Soda is really terrible for you (except this weird sugar-free kale soda, but it sounds disgusting). And guys, we hate to break it to you, but even diet soda isn’t as great as you think.

Here are six things that might happen when you stop drinking soda.

1. YOU'LL PROBABLY GET A HEADACHE AT FIRST

Sorry, this first part’s gonna hurt. If you’ve been drinking soda regularly for years, you probably can’t quit cold turkey without a headache for a day or two. (Diet soda drinkers, you too.) Take an ibuprofen, sip black tea, and it’ll be over before you know it.

2. YOU MIGHT NOT NEED TO PEE AS MUCH

Any soda with caffeine is a diuretic (yep, including diet), meaning it promotes the production of urine in your body and makes you need to pee more often. Like in the middle of a conference call. Or sitting on the highway in the middle of traffic. Or at that really amazing part in Brooklyn.

3. YOU'LL DEFINITELY LOSE WEIGHT

Unless you’re swapping out sugary soda for booze or milkshakes, it’s just science. A 12-ounce can of regular Coke packs in 120 calories, so if you cut out three a day, you’re eliminating 360 calories from your diet (or saving them for dessert, whatever). And according to a study conducted at Purdue University, even diet soda could contribute to weight gain--artificial sweeteners confuse the body’s natural ability to manage calories. Doh.

4. YOU'LL PRESERVE YOUR SMILE

Both diet and regular sodas stain your teeth, cause tooth decay and wear away your enamel. If you quit now, you’ll thank us in 20 years when you can still eat corn on the cob.

5. YOU COULD GET FEWER COLDS

Ever wonder why you’re always the one who catches the bug going around the office? If you drink two cans of non-diet soda a day, the 200 grams of sugar you’re consuming will reduce your white blood cells’ ability to kill germs by 40 percent. Damn.

6. AND YOU MIGHT EVEN LIVE FOUR YEARS LONGER (SERIOUSLY)

The American Journal of Public Health studied the length of telomeres in the white blood cells of people who drink sugar-sweetened soda and people who don’t. Soda drinkers tend to have shorter telomeres, meaning their average lifespan is four years shorter than non-soda drinkers. (Diet drinkers, you’re off the hook.) That’s the last straw--we’re quitting.
