I've started brewing a big pot of mix of loose leaf green and jasmine tea, drinking 4-5 cups has really quenched the 'thirst' for having a late night wine or beer, that I once had.
I used to home-brew wine and beer, and always had a cupboard full of it. Well instead of noticing that supplies were dwindling and brewing more wine/beer, I've let it run out. If I do feel the urge one evening, I'll just buy a 6pack of beer every now and then I think. It will be cheaper in the long run, to shift to this very infrequent mode of drinking
