I had one na beer on vacation, and it was god, but it's not something I feel safe making a habit of. I ask myself if i'm drinking it because it sounds interesting, or if it is "replacing" alcohol. I personally can't drink anything with the thought of replacing alcohol, because my mind goes right to alcohol. the only replacement for alcohol is, well, alcohol for me.
so I don't keep it around. that one I had on vacation was pretty good, but I didn't finish it and didn't get any after that. and I didn't obsess.
guess maybe that's a question to ask ourselves: are we thinking about the na often, as we did with the real deal? does it make you worry you'll relapse, or crave? then it's too hot to handle.
