Ahh-ooo-ga goes the klaxon alarm.

I realise it is early on but you need to consider where you will stand in the scheme of things should you pursue a relationship. The most common situation? That is to become a co-dependent. In my opinion this is a form of emotional abuse. Should he prove to have a drinking problem (which this rings true to me) you will not be the priority.

Consider this, if he had this many drinks on an occasion that normally would have a person on their best behaviour then imagine what kind of drinking happens when they are not trying to impress.

Yep, those alarms and bells are going off.
