Beverage suggestions

Options
I have been doing some goal setting this week and one of the goals that I set for myself is to cut alcohol out of my life for the next 4-weeks. I do not drink during the week however I like to indulge on the weekends. We are very social and alcohol it is usually a part of it. (Hey, I live in WI) I want to find something besides water that I can drink while out and about. I cut out soda in October. Suggestions?
I am also looking for some good ideas to spruce up water. Some refreshing ideas.
