Hang in there - even if you have to say to yourself you will have a drink after you have finished the day with the kids in bed asleep. Then come back here to SR so you can get over that next hump. Heck by then you may be so tired you won't even have a craving to get through.
Each craving you get through will buy you more time until the next one. Everyone who has posted the same thing here is correct - it's hard to believe when you a few days in recovery so you have to let go and have faith in what they are saying.
