I wouldn't go near NA beer. I think that if I tried it I would simply begin to crave the real thing. Holding the beer, drinking it, tasting it and subconsciously waiting for the kick from it would be pressing all the wrong buttons in my brain. Why would I want to risk my heard earned sobriety for a product that frankly tastes like pure panther p***?
The clincher for me is that most allegedly non alcoholic beers actually contain about 0.5% alcohol. I don't want alcohol in my system full stop.
