Just remember it will get better.... you won't always be clawing your way through the cravings. That first day seemed like an eternity for me and I thought about drinking constantly. The second day I didn't feel much better, but knowing I got through day 1 gave me a little hope I could make it through another 24 hours. By day 3, I felt a little stronger, and it kept going like that.....
I spent most of my first few days not doing anything but reading on SR and staying sober minute by minute, hour by hour. Whatever you have to do to get through the day..... it will be worth it, I promise!
