Probably have the best success with Dry Jan if you do different activities versus trying to do the same activities as usual but sober.
Think of something off the wall (for you) that you have never done (or don’t do anymore/recently) and go do it sober. Take a book to a coffee shop, go to a museum, listen to Tibetan singing bowls in the dark (or with candles), hike a trail you have been curious about, ride a bike to go eat someplace, go to an arboretum, sit in a steam bath and/or sauna, read a book in a genre you have always been curious about, etc.
