No I've not taken the pledge, I still enjoy a pint or two of decent real ale.
I do, however, like a few days a week alcohol free. I popped into Tes cos's last night and picked a pack of Bavaria, alcohol free wheat beer, and I must say it is really nice. I've had Bavaria alcohol free lager before and that was quite good. Bavaria is certainly much better than Beck's and Cobra alcohol free offering - it's certainly worth a try.
