Does my mom have unhealthy drinking habits?

Hi. I’m not entirely sure whether this is the correct place to put this but I think my mom has unhealthy drinking habits. So first of all, she starts drinking almost immediately after waking up. She also drinks vodka seltzers consecutively. I think that’s the word, but she drinks another seltzer nearly immediately after finishing the last. She doesn’t drink at work. Anyway, I was wondering if this is unhealthy or just normal. I am also posting this is r/stopdrinking. Thank you, all advice and concerns are appreciated.
