If you really want a rough estimate that sort of gives a decent answer to the question, you can always say “about 5% stay sober.” This is not far from the truth. In all actuality, you can see a sort of drop off rate as people try to stay sober for longer and longer. In other words, if 100 people try to get sober, about 5% of them will make it to 90 days sober.
