Drinking nothing but water for 21 days seemed like it would be more of a challenge at the onset. However, i found it easy and almost enjoyable to drink only water. It felt good to be free of the caffeine, alcohol, and added sugars that plague most of my favorite drinks.
It also changed my relationship with water. I was able to ignore all of the other "choices" in the fridge and stick to good old spring water. I mixed in sparkling mineral water as well as water with fruits added to change the pace but for the most part it was plain spring water.
I will continue down this path of drinking mostly water, but i'm not going to completely eliminate everything. There isn't anything wrong with drinking a beer once in a while, but i don't need it to be an everyday occurrence in my life anymore.
