Open Question: Metformin and alcohol?

I've seen this question a lot, but here only a few from the actual diabetes. My doctor put me metformin, because my pancreas to make insulin more quickly than they should have (I have not really associated with type 2 diabetes have not yet confirmed). Now I generally do not drink, but tomorrow night my friend a couple growing together, we hope to have some fun. I can consume some beer in the metformin?
