Well, it's certainly normal for me.
I've been sober over nine years and still wonder if I'll drink today.
That's why I take it one day at a time.
Today was a rough day, too. Best friend came over drunk and bought a beer to drink at my place. I didn't even want anything to do with the empty so I took the trash out.
I felt sorry for him more than I wanted to drink because he was. It was sad to me.
So, yes, for me it is normal to wonder if I'll make it through another day sober.
But if I keep my priorities in order and 'think' sober. I may not drink today.
Just today, mind you, I don't know what's going to happen tomorrow.
Best to you and if you don't take that firs drink, you've accomplished something.
