For me- sobriety means total, complete and uncompromising honesty- in everything. If I study for 1 and 3/4 hours, pre-sobriety, I would have 'rounded it up' and tell people it was 2 hours. Kind of true, only 15mins right? And of course 2 hours sounds more impressive. Except I am deluding myself- and little white lies then become believe by me, then the lies get bigger- as it was with drinking. I only had 6, not 10 glasses, etc.
If I tell others I have been sober for 3y but had a slip for 2m, then it is crap.
It depends on the mindset. If someone truly believes the info they are sharing is sincere about sobriety time is working for them, in truth- good for them. For me the danger would be two fold- believing such rationalized sobriety time is true and perhaps more dangerously, knowing it is not true to me and my morals, thus causing psychological pain....which can lead to relapse, and for me - death.
