8 Cups of Water A Day

For the past two weeks, I've been drinking a lot of water--8 cups per day, to be exact. I usually fill a water bottle with a pre-measured amount of water in it and then make sure I drink all of it by the end of the day. Surprisingly, it hasn't been all that difficult, especially since I drink a decent amount of water every day anyway. I haven't noticed anything too different other than the fact that I feel refreshed when I drink water. I think if someone who doesn't drink water often suddenly switched to drinking 8 cups a day, he or she would definitely notice the more frequent trips to the restroom.
