When the pandemic started, my husband began making cocktails before dinner (with a small bowl of Goldfish), in addition to the usual wine with dinner--one or two glasses. We never got drunk, but as you say, pleasantly buzzed.
We also (predictably) put on some weight. My husband, who has always been heavy, was finally ordered in the strongest of terms to lose weight.
So, around mid-December, in addition to being more mindful about what we ate, we stopped the cocktails and Goldfish. We stopped drinking wine. Except for a glass of Prosecco on New Year's Eve, we've been dry ever since. I missed it at first, but no longer do. He's lost about fifteen pounds, while I've lost a measly five--but I'll take it.
Mine is sugar--probably more socially acceptable than alcohol, but arguably no better for my health.
This is my drug of choice, too. And we haven't had much of anything sweet since Christmas (a few cookies). This is harder for me than the alcohol, because baking is one of my passions! I do bake all the bread we consume, though (whole wheat, rye, bagels, baguettes, you name it, I bake it). But desserts, cookies, etc.? No. And I miss that very much.
