partners question???

I've been with my husband 11 years now. It's becoming a regular thing now but when he drinks with or without me on a night out he has a personality change. We leave our house happy and together a when we get back he's angry at nothing and making comments to me. He did it years ago and it completely stopped but recently this is happening too much. I struggle with anxiety and it's affecting me. I tell him the next morning what he's said and he apologises. Is it mixing drinks, not eating enough. I need advice please
