Welcome back C4G. Admitting you drank is difficult, kudos for doing so. As far as words of encouragement go, I think you are already aware that you have the tools and strength you need to stay sober, your past has shown that.
Regarding your first comment though, i hate to break it to you but you have to take the bad with the good. It's certainly helpful to move on and look at the positives, but we need to learn from our mistakes too. You say that you have a plan and are working with your doctor, but obviously your plan wasn't functioning last night. Look back to see where it went wrong...most times it's well before the actual act of drinking takes place..sometimes weeks before.
I noticed that you haven't been on the site in several months either, was SR part of your plan? If not maybe you could add some daily time here -I found it to be very beneficial for my recovery, and still do.
