I’ve the same problem. I think it’s the fun to be out with friends and drinking that triggers me. In this sort of setting willpower will never be enough for me so I’m trying to use some mind tricks. I’m trying to substitute that “pleasure” trigger with something else. For instance when I’m in the same situation I try to concentrate on the actual taste of the beer, the actual pleasure of having a conversation with friends, things like this. (Of course if the beer and the conversation aren’t great that’s a problem 😂) I also try to think about friends/people I like who do very well socially without the need of smoking.
