It’s hard to stop once I start

I (26F) would like to preface this with I recently lost my mother to alcoholism and dealt with abandonment from her due to alcoholism.

I do not drink every day. I do not drink to be drunk. I do not drink to get rid of feelings.

I typically only drink in social settings and around my friends. Sometimes if I’m bored around the house or the weather is nice I drink alone.

The problem I have is when I have a drink it seems hard to stop. I don’t LIKE being drunk. My goal is never to be drunk.

But once I start getting buzzed, it’s like I can’t stop. I can go out to a restaurant with my friends and have a drink, then go home without drinking anything else. But if I am in a bar setting or around people who are having multiple drinks I can’t seem to contain myself to stop.

I never drink to obliteration or black out and I do not drink and drive. But it weighs on my mind heavily that alcoholism runs in my family and caused a lot of trauma for myself and my family. Is this a sign of alcoholism?
