To me they were pretty awful. In my first one it lasted like a year and I was horribly paranoid, up every night with vivid tactile hallucinations of being sexually/physically abused by demons, believed devil was going to kidnap me and take me to hell to impregnate me w antichrist, was reading messages in the clouds and believed they were the devils agents, was talking to god, angels, demons, ghosts, etc. Did a ton of bizarre things to keep myself safe, was also having visual hallucinations, it was just insane. My other two weren't as bad and were shorter, just 2-3 months, and one I believed I was going to be a warrior in the apocalypse and that another demon had come to harass me, was up all night repeating bible verses again, running around the apartment at night being chased by the demon, scratching at my head to stop the voices, going to church every day trying to ward them off....then the third one I was terrified people were going to hurt me and hid in my apartment and then thought people would climb in through the window (I'm on the 9th floor) and that people on the internet were watching me through cameras.
So yeah not good. I've been on Abilify (10 mg, wasn't very effective), Risperidone (2 mg? Don't remember but it worked very well) and Latuda (40 mg? I don't even know it was a lower dose though. Maybe 80 mg actually).
I'm high functioning and also have many good coping mechanisms that I built up from a lifetime of dealing w these symptoms. Last night I woke up w paranoia and saw a demented alien/scarecrow thing staring at me w its head backwards and upside down and I laughed and called it a b**** lol.
