How often dose a person dtink when s/he is in the first stage of alcoholism

The early stages of alcoholism are often difficult to detect. During this stage, the addicted person’s body is building up a tolerance to alcohol, so they may be able to drink larger quantities without losing control.  

If he/she is doing it daily or if every time they are drinking they are drinking to the point that they can't work or do daily activities. But honestly in my opinion, if someone is drinking to a point where it is getting the way of things being done and is making you question if your one, would mean you possibly are one.
