I am not sure there is such a thing as a 'normal' amount.
If you are trying to see how you stack up, don't. Comparing yourself to others is never helpful. Even among the people here the differences in how much we all drank is staggering. There will always be someone who drinks more than you and someone who drinks less, and both will serve to justify your own intake. I think if I spent less time comparing myself to others and more time examining my own relationship with alcohol then I would have quit way sooner.
Hope you are well Bruno x
