I tried it in my "dry January" nonsense on a night out and wasn't impressed. Also had a Becks Blue (awful - like stale fizzy water!) and an alcohol free Kopparberg cider which tasted exactly like the real stuff (sweet enough to make your teeth itch).
As mentioned a few times the Ghost Ship is a cracker, I spent a new years eve on that stuff as the designated driver and it was perfect. Yes it's still .5% alcohol but you'd need to a drink a case of it to be over the drink-drive limit. I had 4 or 5 stubby cans and still felt like I'd got a bit of a buzz from it - placebo effect I suppose, especially carried away in a crowd of drinkers. The actual alcohol content would have been like having a half of shandy!
