Teetime and Davidal: I, too, am going to try for a Dry January. Like Teetime, I usually have a glass or two of wine nearly every night - and it's got to stop! (But not until Monday 6th, as we've got family birthdays this weekend.)
I did have a Dry October, which was very insightful for me. Now, to explain this: I don't have a problem with not drinking for a few nights, which I often do. But I've never gone without alcohol for a whole month for years! (Never felt the need to.) I felt so different - not physically so much as mentally. It was really weird (and very unexpected). I felt like a different person inside my head, as though my thought processes and patterns had completely changed. It's hard to explain this. But it was a bit of an eye-opener to have the evidence of just how much alcohol affects us. (Just one or two nights off-the-plonk doesn't have this effect - but a whole month certainly does!)
So looking forward to doing it again - and who knows, maybe I'll stay off for good ...?
Good luck you two! (And good luck to everybody else with their New Year endeavours.)
