I wouldn't recommend beer at this stage. The gas from the bloating will be awful. I am a month out and I totally understand how u feel. If u really must, take a sip...one sip and the craving will go away.
Hang in there. Old habits are hard to break. Don't throw your hands up and say, well I messed up so I might as we'll. just begin again. You will do well. Just take it one day at a time
