I might fall into this camp. I have been med free most of the two years since my diagnosis. I did not maintain any semblance of stability in 2015 (hypo->mania in Spring, crash to depression in Summer->Late fall), but since then the mania and psychosis really scared me straight and I have kept stable all on my own. This past month, I've basically felt 'euthymic'. In 2015, I knew to reach for the zyprexa PRN, which knocked me back down to earth but it was pretty late. Part of why I think I waited too long that time was it was dysphoric so it was harder for me to see (my first mania was euphoric). I think the question is if you can trust yourself to see that you need an AP. There are clearly people who can't be talked down from mania, and I'm not saying it was that easy for me at the time.
