Zenchaser, when I made my plan, my commitment, my vow, to quit drinking, I never considered the possibility of drinking again. There was going to never be a slip, a relapse, a plan B. I was all in. I was given a chance to quit drinking, and I treated this chance like the last chance. Quitting alcohol for good was an event, not a process for me.
When you do this, you will have reached the top of that mountain, with a vista that shows you where you have been, and the complete range of possibilities open to you. You have made it to the top, you have quit. Now you know you have no limits, that you can conquer this fear and make simply massive changes. You can move forward in any direction you choose and never ever look back.
You have done it before as you say. You are awesome, Zenchaser. A true badass. You got this.
Onward!
