Do not be too hard on yourself.
Alcohol addiction is cunning, powerful and baffling.
I myself can not have any alcohol in the house as I know how easy it is to be tempted.
I often hear in meetings how people have picked up drinks without even a concious thought.
Unfortunately that little bit of alcohol will set off those little monsters in your head. They want you to keep drinking but remember you are stronger than them. Do not give in to them.
Every day you are free from alcohol you will get stronger... it is a steep learning curve sometimes. This being one of those times... we all make mistakes, just remember to learn something from it... no more alcohol in the house. ( I learnt this one the hard way too )
Stay sober, a beautiful life awaits you... you are worth it.
