Very rarely as my partner hardly drinks at all and I haven't for nearly two years now. What is interesting to me is I was in a pub last Saturday night after a meal with friends and it did me a lot of good to see people sitting around drinking. It reminded me that I'm not missing anything.
Didn't tend to go to pubs while I was drinking except to start a session (one or two) before going home to get smashed as it was cheaper and more secluded so less chance of being seen or getting into trouble.
