How long do you stay on an elevated dose of antipsychotic after an mild episode?

Back in January I had a hypomanic episode so my Psych and I increased my antipsychotic. My symptoms of the hypomanic episode have resolved. Recently in the last week or so I have been feeling physically heavy, weighed down, I think it’s the higher than normal dose of my antipsychotic.

The last episode I have before this most recent one had been really severe as it was before I was diagnosed nor medicated, I was psychotic and in a mixed episode.

At that time my Doctor wanted me to stay on an elevated dose for 6 months before lowering it very slowly.

How long do you stay on an elevated level of antipsychotics after a mild episode?
