Cannabis? People will frown, and I know it is just replacing one substance with another, but vaped it is probably less harmful.
A really nice coffee, maybe gives a bit of a buzz.
A hobby you actually really enjoy?
Sometimes a really engrossing series or something can help.
Something you really want that you could set aside the saved money and spend on? holiday?
A reason not to drink, for example sign up to an early morning class you enjoy? Or just get up and go visit someone, who’s not a drinker.
Honestly, it can be really difficult. I know myself, I have to really grit my teeth to not drink especially if stressed. But some days I manage it with the play it forward technique I’ve heard. So okay drink may seem to destress for a v v short lived time, then you just get sloppy, feel ill, waste money and time, and ultimately probably increase in units will likely be needed to get the same effect, and with that comes health problems and misery. I try just grit my teeth, and you kind of get used to not using it to destress after a while.
