NA beer has like 0.5% or 1/10 of your average beer. So you would 10 of them to get the effect of one. I think trying it out isn't a bad idea since the concentration is so incredibly low. But, it may spark the desire for a real beer. Or, you may say that it is enough. It's all trial and error. Find out what works for you.
I prefer mineral water like La Croix when I am out by the pool and everyone else is drinking. I pound like 10 of em! No salt, sugar, or any additives.
