I've heard a lot of people say that they went through something like a mourning period when they quit -- as if they were losing their best friend. (I didn't -- I hate my disease and I'm grateful for every day that I live without it controlling my life). But I do understand that a lot of us use alcohol to fill a void inside us. The alcohol may be gone, but the void is still there. That's where things like AA and this place come in handy, to fill the void with something positive, like hope, support and love. Try to get out of your head as much as you can early on. Reading, walking, helping others, anything that keeps you occupied and feels rewarding when you're doing it.
I ate almost non-stop to begin with, but it tapered off. I think that's normal for a lot of us.
I'm glad you're here FD. Just don't drink today.
