It's only feeing like a reward because it's satisfying your craving.
I used to kid myself that I deserved it, I'd worked hard at work all day (well, a bit in the morning until the pub opened, but meh!) and deserved that bottle or 3 of wine in the evening.
Next thing you know you're waking up and counting the bottles to make sure there's enough left over for the next day and to see what you drank because you can't remember much after the evening meal.
It does get easier, and eventually gets to the point when you're so glad you don't have to drink any more. You don't need the drink to unwind, because it's the drink that's winding you up in the first place.
But you know all this - that's why you've found this place and made it to day 2, I think that's the hardest part of the journey, the deciding to set out in the first place, the knowing why you need to set out, and actually doing it.
Many people don't make it as far as that. Well done, keep on buggering on.
