I really relate to your situation. Make sure to come up with many different strategies and plans on how to spend Friday before it gets here. Right now for me I made a list of all the self indulgent things I enjoy that aren't alcohol related ie fav snacks, fav pop, fav shows, crocheting, new book, variety puzzles, adult colouring book, new apps ( I'm quite fond of escape games and they keep my mind busy) etc etc. And I do these things that I enjoy and for me it helps me feel less deprived. Anyways that's just what seems to be working for me for now, stuffing my face with decadent chocolate lol
