It IS tricky when drinking is a huge part of the connection. Right now as I type this, my husband is on his first (maybe second?) beer. He will start to feel chatty in a bit in that initial euphoria, and I don't feel chatty, or particularly euphoric.
So yeah - tricky.
Not impossible though, and I won't drink just because he is drinking. Ultimately it's always one's very personal choice to drink or not to drink and this is a thing which sounds really basic, but to truly realize this means you are then responsible to shoulder 100% of the work necessary to remain sober.
