I am prescribed an antipsychotic medication for a very mild bipolar disorder. Ive stopped this medication before with no major side effects. The half life of my antipsychotic is 18 hours. My question is how long will it take for this antipsychotic to not only not be active, but no longer working as an antagonist to my 5-HT receptors in my brain? I plan to use a recreational drug that is completely diminished by my antipsychotic and want to know how long it will be approximately until I can use that drug with very little diminishing.
