I feel real strongly that one person, sponsor or no, should tell another to reset their sobriety date because they experimented with NA. Like yeahgr8 mentioned, a person might decide to do so themselves .... Recovery is an inside job.
I stil have an NA beer now and then, less so as time goes on. I prefer a sprite zero
Deciding that you are not alcoholic because NA wine doesn't trigger you, or you seem to be having an easy stretch so far... No. Maybe you aren't sure yet. Maybe you aren't done drinking. Maybe you are not alcoholic. It's an important journey to your own conclusion, and if applicable, acceptance. That journey doesn't involve NA beer or wine.
If I have an opinion about you, in particular, regarding NA beverages... IDK, maybe you ought to wait until you've made that journey.
Peace
Mark
