Yeah I've switched from risperidone to Abilify/aripiprazole to quetiapine/Seroquel and back to Abilify without a hospital stay in sight
It sounds like you'd rather go back inpatient though because you're scared of what might happen? Keep in close contact with pdoc and see how it goes. Hopefully you'll be fine and won't need to go back in, but there's always that option if you need it.
All the best icky
