You will be fine. Very normal. No reason to get anxious. Our brains like to give us the worst case scenarios and worry us to death until we grab the bottle or a pill again to ease the mind and make everything okay.
If you are an alcoholic, focus now on treating the alcoholism that made you drink. For me it is that negative feedback loop in my brain that plays out every worst case scenario and convinces me that everything is not alright and all is about to go to heII and a hand basket. That then manifest itself into this feeling of impending doom deep down in the pit of my stomach.
You treat that, anxiety and the NEED to drink will magically disappear or slowly vaporize into thin air.
