I gained my weight in the years after I stopped drinking alcohol. Go figure! I guess nothing is safe.
I love beer, too. Some abstainers think the non-alcoholic beers should also be avoided, but I like to have one now and then. The ones I like best are St. Pauli Girl N.A. and Clausthaler. O'Douls tastes like crap to me...
There is as much alcohol in a non-alcoholic beer as in a carton of orange juice. In other words, not much.
I know there isn't alcohol in it because I'm only interested in drinking one.
I have not had an alcoholic drink in 28 years. And I'm none the worse for it.
BTW, one doesn't have to be "an alcoholic" to stop drinking. Plenty of people do so for health reasons, religious reasons, and so on.
