I had one real episode then a little relapse about a year later so I had to wait two years before coming off the meds. I was scared too that I would go back to how things were during my psychosis. Tapering off the meds is a pain...it's like you're not yourself on some doses. I'm currently on 2.5mg of abilify which is a quarter dose....probably not protective against psychosis but I'm fine better than I've been in two years. I feel like me again, it was like the medicine had slightly changed my personality and now I'm my real self again. I was afraid to go off now I'm hating what the meds did to me.
I have a thread titled these aren't candy that went through my conflicting emotions on the process if you want to look it up.
