Lady you are better than this cycle you are in now!
But...you can get back to the healthy routine you were in before.
I think if it were me, I would just throw my all into getting a day 1 done.
For me the first few days of not calling in the supermarket for a bottle took work.
But once I had done it a few times it got easier.
Some days I would just go to bed early if it meant it got me another day done sober.
Don't be too hard on yourself.
We all have vulnerable times when its harder to keep on going drink free.
But I'm sure you will feel happier once you are back to where you were.
You can do it, I have no doubt.
