Be careful Darkling...that is exactly how it goes at first. Feeling good does not make staying sober easier, after the first blush. On the contrary.
Is there someone in your face-to-face life you can rehearse that plan with? Gives a plan flesh on the bones, I find. I have to tell a trick I have developed: I have to seize a moment when I am clear enough and content with sober enough to share my specific plan with someone. If I wait til my partner gets home, or wait for anything, really, I might have gotten all secretive by that time about my desire to drink. Instead, when I just start to dwell on something stupid, I literally force myself to text out to my partner my plans for the event or the day or later tonight...whatever is starting to get to me. Just a couple of bullets. It pulls me up short. My partner would not try to enforce a plan or bug me about it. So for me, it is a way of mentally checking myself.
