I honestly do not understand something here.

How can an AP be taken PRN? Isn't the whole point to avoid psychosis? How can you remember to take it in the middle of a psychotic episode, a paranoid delusion for example? By then I would think its too late. Don't APs take awhile to work, like on the order of half a day or more? How would this play out at work?

I am glad I do not have this happen to me!
