It is common to see vapers in bars/clubs here, so luckily I haven’t had to deal with the social acceptance issue, which is also supportive.
I started vaping 3 months ago, but still smoke 3 cigs a day. However, I was chain smoking when I went out drinking. I also had batteries die or coils go out, and I ended up bumming smokes. I was getting discouraged, so I came to the forum and read up on vape/beverage parings, etc..
Mostly I drink beer, quality stuff and cheap stuff. It was suggested that I try tobacco flavors, which I don’t usually like, AND up my nic levels while drinking. It seems common to vape citrus while drinking, but I have not tried that yet.
Although I’m still smoke when I drink, I have cut it way down. I’ve been using Custards and a Turkish Tobacco. I also have a Blue Honey that goes well with Coors Light.

The higher nic, while drinking, also seems to help. Last, but not least, I always bring 3 fully charge batteries and 3 full tanks, so I don’t get in a jam.
