Sounds like you are in a lot of pain over this!
I hope you have a real good look at why you drank again and im presuming you are in AA so hope that you rework the first 9 steps again asap with a sponsor!
I "know" people that drink NA stuff, one person a bottle of NA wine a night, they have 15 years sober and sponsor which is quite "funny"...their sponsees are as loopy as them but thats not my concern...what is my concern is to ensure i dont get like that!
A 24 hour period of sobriety? Well either God (your HP) has removed the obsession to drink or hasn't and i know that He does not work on the 24 hour clock! Sure living in the day in an excellent goal and well worthwhile but you may want to take a look at that too IMO...
Best of luck...get on with some work so the **** its dont come back and you find yourself crawling back asking for help in a few years if at all...
Obviously your sobriety date has changed as it is the last time you chose to drink alcohol...up to you what you do with that though!
