If you're finding it hard to give up booze for the month you might want to snap up a bottle or two of Waitrose's low alcohol cider which is only 1% ABV.
Now I'm not saying it's the best-tasting cider ever - it's a little too thin and too sweet, for my palate at least* - but it does taste recognisably like cider in a way that apple juice doesn't and if you were drinking it with roast pork, a chicken casserole or even a nice hunk of cheddar it would rub along fine. It's actually made in Herefordshire in old oak vats so I'm guessing it probably comes from Weston's.
The price is pretty attractive too. It only costs £1.15 a 500ml bottle - online at any rate. I somehow ended up paying £1.21 for my bottle in store, maybe because it's classified as a 'Little Waitrose'. Not a huge outlay anyway.
* However my neighbour who just popped in tried it and said 'really nice'. So there you go. I should also have pointed it's 180 calories a glass so it's not exactly a low calorie option - though not much more than a large glass of shiraz.
