It is very annoying when a person drinks too much and somehow wants to push you to follow their example, especially if you don't like to drink alcoholic beverages or you like to stay alert and for that you have to stay away from alcohol. When that has happened to me, I simply try to stay away from this person and if he/she is close to me I try to take him/her away before he/she continues in worse ways or I call someone to come to rescue him/her and I leave if possible, greetings!
That's a good plan, limiting contact with people like this I mean. They're often idiots anyway, and I have no time for idiots.
