So ive herd many people saying you don't need 8 glasses of water per day,you only need that much in fluids AND coffee doesn't dehydrate you, but just makes you pee more. So, I combined both of these experiments into one.
The past 5 days I've replace all my fluids by coffee alone. The rest of my diet remained the same. Here are my results:
I feel like HELL. MY throat is always dry. The first couple days I peed a lot, now I'm back to "normal", either because I just dont have the fluids to pee, or Ive equalized. My skin is the driest its ever been. Its actually peeling in places. Despite all the caffeine, im REALLY tired. All the time. My vision is slightly blurred. My sleep schedule is horrid. I wake up every 20 minutes.
Conclusion: DRINK YOUR WATER sans caffeine, every day. This experiment blows!
