having trouble sleeping i would say is normal at 5 days. I don't know how much you drank but I would imagine your body is not used to being without alcohol. Unfortunately you will have to ride it out, but it will get better. As for the mood swings that too is normal. Working the steps has showed me that I am imperfect by design, and having emotions like anger, stress, sadness, loneliness, and irritability are too normal. But now I learn how to deal with them as opposed to stuffing them inside.
