I'm hazarding a guess that you are being touchy…?
Whatever the case, your question is not specific enough for anyone to really provide a sensible answer. It needs more context, and you need to clarify whether your question is seeking an answer about social norms or psychological/physiological outcomes. Assuming you mean psychological/physical, even then you still need to be more precise, e.g.
"AIBU to think that drinking every day and they can't go without it, even if it's only a couple is excessive?"
"…drinking neat shots of absinthe every day, even if it's only a couple is excessive?"
"…drinking on an empty stomach in response to stress every day when it affects them mentally/physically quite badly, even if it's only a couple is excessive?"
Otherwise the answer is really always "it depends". That's because "excessive" is defined on a case-by-case basis for each individual. Some people could drink two strong shots every day and their body size/ethnicity/temperament/mental health/liver will allow them to get away with it. Others could have two weak beers every day and die of liver complications at 50.
In short, to answer your question: it depends.
