Jay - you know it won't be just one day. Thats the addictive voices in your head trying to tempt you back to booze.
It will turn into days, weeks, maybe months.
You have worked hard after your hospital admission, but you are probably still a bit fragile after drinking for so long.
Don't isolate yourself.
Why not step up your AA meetings if you can, perhaps go to 2 meetings a day?
Could you confide in someone at AA and say you are having a hard time and see if they could meet you for a coffee or help keep you occupied?
Are you looking after yourself well?
As in eating good and resting and getting enough sleep? Maybe thats something that is causing you to feel like this?
I really hope you come here more, especially when you feel like this.
If you drank for a long time, its going to take a longer time to get used to not drinking and your body recovering. It won't happen overnight. I'm sure you know that already.
I wish you the best xx
