"I think I've come to a decision i've finally set a date to stop drinking..."
I commend you on your realization that you have a problem and you intend to address that problem.
But, please don't take offense, my ears are pretty much closed to what people 'intend' to do about their problems 'next week', as they sit feeding their problems while they mention their 'plans'.
Do something about the problem down NOW and you will be days ahead of schedule when the planned date comes.
Regardless of what I think though - best wishes in success with your situation.
