I suffer psychosis but don't want to take medication all the time, is there a way I can just take pills when I'm suffering and not when I'm fine?

See answer. For these medicines to work well you have to take them every day. Your condition is like someone who has high blood pressure or diabetes, they need to take their meds everyday. Yours is not like a mild case of asthma where you could just take meds as needed. Taking meds everyday will hopefully reduce the the amount of time you spend in serious suffering. This is again like a diabetic patient.
