I have taken aripiprazole 25mg and olanzapine 15mg for a few months for my OCD. I realized that aripiprazole was not working for my OCD even in such a high dose. Then my psychiatrist directly switched to risperidone and she put me on 2mg b.d. (i.e. 4 mg per day). I am now on Day 3 taking risperidone. I found risperidone a bit activating and has caused insomnia (early wakenings and having difficulty falling asleep when taking a nap). Is this caused by risperidone or is it simply a withdrawal symptom of Abilify? Which option should I discuss with my doctor?

Option 1: Wait for the insomnia to subside
Option 2: Increase the dose of risperidone
Option 3: Take 4mg risperidone in the morning
Option 4: Take 4mg risperidone in the evening
Option 5: Increase the dose of olanzapine
Option 6: Switch from olanzapine to quetiapine
Option 7: Switch from risperidone to quetiapine
Option 8: Switch from promethazine to hydroxyzine
