Much like @SweeperDee and @Mr. Alli my go-to in stressful times has been the drink. I had cut down massively but the last few weeks I have been well back up to previous levels.
I start at 8 pm but the quantity I put away between then and, say, 10.30 is staggering. Last Saturday I had about 3 and a half litres of San Miguel. Well beyond normal for me. When you can sink a can in 15 minutes and head right for the next then you know something is off.
Got to the stage I stopped buying it. Trying to stop myself in advance and that sort of worked. If there are no cans in the fridge I can just avoid it. Not the best strategy, but it gave me the odd night off. Daytime me trying to protect nighttime me.
