For me personally the PRN AP are used for sedation for me to get through tough times. Its to bring the level of distress down until I am able to cope again. I have used seroquel PRN for years and years, it is a very good medication for me to be used that way. When you use small doses not regularly the sedative affect tends to stick around. I rarely use the seroquel long enough for the sedation to wear off (and if I do I just up the dose, it stops being sedating at around 200-300mg and starts then working as an antipsychotic rather than a tranquiliser). I have a full time AP so using seroquel this way works for me. I doubt I could do the same with Zeldox, different meds would work in different ways.

I have also used xyprexa PRN too, love those wafers but glad I have not had an episode where I have needed them for a long time. They are quick and effective treatments for people who need something strong to work very quickly.
