Hello and welcome.
I so remember being where you're coming out of; living to drink and drinking to live. I felt so hopeless until I found my program of recovery.
I don't know if anyone else tried this, but I drank warm honey and orange juice a lot when I first stopped drinking. It helped with the sugar shortage. I also ate several small meals a day, lots of carbohydrates, as I had lost so much weight. I tried to not make a big deal out of anything, lack of sleep, lack of appetite, lack of focus and comprehension. Be gentle with yourself. It'll all come back. It just takes time, like, one day at a time, doing the best you can do in the early days. Just don't pick up that first drink and you'll get your life back. Good luck to you, and positive thoughts coming your way.
