I installed a sobriety tracker on my phone. It says I've saved $300 and not consumed 200 drinks in 18 days. $300 seems a little high given how much I make but 200 drinks seems about right. Also 30,000 calories avoided.
I spent 99 cents on one I think called I'm Done Drinking. I'm using a free one called Nomo now. The first one wouldn't let me set the money I was spending low enough but it tracked calories. Nomo is prettier and more full featured really.
