Hello dear, Interesting question...Common query  though...See being a functional addict of something is usually the demand of someone coming out of substance use or dependence...But you have to understand the gravity of the situation that since you have suffered an episode of psychosis? Depression?( As escitalopram was  also prescribed)..you are more prone than others for future similar episodes with any substance...Your doctor will explain you that.. Exercise regular meals and sleep well will help for sure....So Consult a Psychiatrist for detailed evaluation and Management of the case... Kindly give time to  your body,brain to readjust..ok
