If it has been 7 days since your last drink, it is normal that your emotions and psychological state are out of tune. Plus, if you were a long time drinker, it will take time for things to reset. I'm glad that you are 7 + days of sobriety. You are doing it and that is what counts.
I read your previous post about how you were thinking of alcohol and i'm proud that you were able to resist the temptations. Just on my way back today from trying to attend an AA meeting, it seemed that I could spot every liquor store along the route. The weird thing was that I have never been in that area but the liquor signs just popped out. Remember the event that you were tempted tonight because more than likely it will happen again. Then when the event comes up in the near future, you can reflect what you did in the past and overcome it AGAIN.
