Breaking the habit around booze

I've massively cut down over the last five years. I now only Smoke when I'm boozing, and then only when I'm out (a glass of wine when at home doesn't usually have me reaching for the cigs, although a few glasses might).

My problem now is how do I pack them in while out? It's definitely habit, not nicotine addiction, so nicotine replacement or vaping aren't the answer. My problem it's there's so many great reasons to smoka when drinking (smoking areas Are usually best craic in nightclubs, and it's a great way to interact with the opposite sex). Anyone have any suggestions?
