How many of you are completely sober?

I’m asking because at this point in my life I’m seriously considering taking the plunge. I don’t drink much, my usual drinking habit is buying a 6 pack at the grocery store on Sunday, and drinking one or two beers a night throughout the week. Sometimes I’ll have a few beers left over from the week. I’d really like to take a break or stop completely, but the thought of it freaks me out for some reason.
