I've been on all three of those meds just not at the same time. I'm still on Invega. Fluoxetine made me manic, olanzapine made me feel just the way you're describing. I'm on a good mix now with vraylar, invega, and lithium as my main meds and really no significant side effects except some dizziness and restlessness and neither really bother me. Tell your doc how you feel and see what they have to say.
