Day 4 was a turning point for me.. Know what you mean by the positive feelings/return of motivation. Given I've had many day 4s lol. But this time I felt so good, work was good, working out and not being hungover was good, everything so good.. I said f it and now I'm 25 days sober. Don't plan on goin back. Good luck and congrats to you!! Keep it up the days fly by and it gets better and better..
