Last year was really bad for me from an anxiety standpoint, which in turn could have been bad for my sobriety if I would have let it. Thankfully I did not.
When I was drinking though, the lions share of my consumption was done at home/in privatej. And at least around here, the liquour stores, convenience stores and grocery stores were always open - even during the height of lockdowns. So access to alcohol itself would have never have been a problem. Also, other than during a few months in the spring, even the bars around here were open during most of it - including all of last fall when the really big surge of cases was happening.
