Welcome Tog! You've come to the right place. And 11 days is fantastic.
For me, Sundays were recovery days as I usually was drunk from quitting time on Friday until now. Usually needed at least a few beers on Sunday just to calm the shakes and anxiety and so I could sleep and be "ready" for work on Monday. Grateful I don't have to do that today.
Keep posting! We're here for you. Someone is always around.
