Different campaigns - different states of mind, different atmosphere, your mood, and more. Apparently, the brain works differently, and alcohol also works differently from this. Let's say the fun intensifies, the boredom is interrupted by sleep, but something else doesn't work at all, so you don't get drunk.
This effect has been haunting me for the past 50 years. The connection between the amount of alcohol, company and the consequences exists - proven more than once. An instinct has already developed, almost unmistakable. Just sit down at the table - looking at the company already I know the consequences and try to control myself. 80 percent hit.
Conspiracy! Your friends are not plotting anything bad ...
But some personalities prefer to sprinkle or add something to the drink in moments of your inattention )
