Something concerning

Zerenity
My boyfriend and I have been dating for about a week now. It's long distance due to work matters. He says he is drinking every night about just one or two beers and I understand his job is stressful, but last night he said he had drank too much, the other night I was in the hospital and he had taken his anxiety and sleeping pills even though he drank. Should I have a talk with him about my concern that he might becoming an alcoholic? I'm really scared and upset. I don't know what to do.
