Well done on 1 week! For me that was the hardest time of all, irritable, tired, not sleeping, craving like crazy every evening. It's not been a piece of cake since then (7weeks), but a lot easier than that first one.
I think to get through a week is serious achievement, hold onto that.
Nothing Jackass about trying to get sober and having a little faith that this has to improve things. Good Luck
