This is a pretty hot topic around here, you can find a multitude of discussions about if you search the archives Talana.
Contrary to and against the recommendations of some I do consume NA beer from time to time. Never "alcoholically" like I did with regular beer though. I have half of a 6 pack in my fridge at home right now that has been there for a couple weeks at least. I do enjoy the taste along with certain foods and find it refreshing. Having said that if I ever found myself drinking large quantities of it or obsessing about it, i'd probably quit having it around. And I also understand that there are many who might find it way too tempting and have it turn back into drinking the real thing in short order.
Every person is different, you need to decide if it's a good idea or not for you. Probably the biggest question would be your motivation for drinking it. Just for the taste, or to help feed some of your old habits/cravings?
