I went two or three years as the longest time without relapse although I was not perfect, and the longest I went with sz symptoms without treatment was between 2009 and 2015. And the longest ihave gone with treatment without relapse is 2016 to 2021.
I was on abilify for 10 years without a relapse… I was on 10mg for the vast majority of those years except the first 6 months when they tampered with the meds.
If by “relapse” you meant having to go to the hospital, it would be 7 1/2 years for me. There have been times when I was getting pretty pathological, and nobody knew about it, though.
I got diagnosed with psychosis 2018 I came off my medication in 2019 after being on it for around a year didnt stop abruptly tryed to cut the dose myself without the docs advise and went roughly 6months and had a relapse before Christmas
I haven’t been hopitalized in the past 10 years. I had some psychotic episodes in that time but i learned to help myself. I done changes in my social network and learned a lot from the internet.
