Anyone want to start a no diet soda challenge with me?

Options
I admit, I have an addiction. Well, besides my terrible food and sugar addictions. I LOVE LOVE LOVE diet soda. I have read so much research about how terrible chemical sugar substitutes are for you and the benefits of course of drinking water. So, I really want to kick this habit but would love to find some accountability on here. Here are some basic rules to start...let me know what you guys think and who is on board with me.

1. Make water your first beverage of choice.
2. Unsweetened tea and coffee are allowed as well.
