Agree with you, was back in the UK for a visit recently and the pubs are reinventing themselves to stay alive, so selling bottles of wine and cocktails, etc.
Pub culture seems to be growing again, but supplemented by much more normalised home drinking.
The fact is I can't drink normally and was drinking socially, but like you had retreated into drinking at home alone.
Happy to be moving away from that again and trying to make new memories
