Curious about your age? Does this get easier as you get older? I stopped drinking for 6 months and then a friend got a new job and my birthday rolled around. I felt like the situations called for celebratory drinking or that it was expected.
I really enjoyed my period of non-drinking and I feel exactly the same as you in regards to sleep, anxiety and well-being. But being in my late 20s I feel like people around my age just expect drinking and going out.
