Motivation for me in early days was being on here CONSTANTLY and engaging with threads. I also changed up my routine, lots of baths, walks and working out. Slept as much as possible, put myself to bed early if needed. Took it one minute at a time.
You might find some inspiration here for Friday …
Another thing to maybe consider is there is always going to be an excuse/reason to drink…Friday, Saturday, day ends in ‘Y’, wedding, dinner, funeral, party, game, bad day at work, good day at work, work is over, you name it, folks drink at it. The thing about getting sober is understanding that that is only how we have been socialized or how we grew up. There honestly are billions of people who don’t drink and we can and do learn how to navigate our lives and situations without alcohol. Strange, but true! 
We start working our sober muscles and they grow. 
You can do this!
