Jack, I was in a similar place regarding your H&F statement not long ago.
I have halved my standard drink intake to maybe ~20 a weekend now and I feel SO much better on a daily basis now (probably due to sleeping better on the weekends).
What helped me curb the rampant binge drinking/partying was a renewed focus on software projects I had been meaning to work on, and training for local races (10ks, half marathons).
I am sure you will succeed as you have already identified what you can divert the time and energy to.
My thought is, maybe you are too good at your current role?
Ive heard of good performers not getting promotions because they are needed to maintain performance in their current team. (not in a software company)
My current pre-quarantine schedule was:
Morning 1x long black at a cafe near the office with a colleague
Rest of work day (plus minus 1 on each item) 2x long black from machine in the office, 1-2x long black with another colleague(s) at a cafe
Home (around 5-6pm) 1x long black
Current WFH schedule is: 2-5x long black roughly every 90 mins.
I enjoy the ritual of making it (plunger) and the warmth. I don't think I get a buzz anymore, but the odd time I do, I love it.
I don't get any noticable side effects, and have gone periods 1-4months without drinking it with no adverse effects.
