Well 13th, take the new job....it sounds like an amazing opportunity.
There is NO point being unhappy in your job and drinking over it.....maybe this can be the new start you need to make this change.
As Dee said, you can get sober in a new place or where you are, or you can keep drinking anywhere....from my point of view, having made so many changes in my life, it did not help me to stay sober. Not at all. I felt way more stable in my recovery at 2 years than I did at 3....the changes were hard for me, and I was kind of lost a lot of the time. Would have been easy to walk down the street to the bar/restaurant.....I love the place. Gorgeous atmosphere and nice staff.
I guess I am trying to say that I think the new job will be great, but I also think you need to make the decision to leave the drinking behind. Change is not easy, no matter how awesome it is, and having a clear head and healthy lifestyle RADICALLY helps.
