My medications are: latuda 10mg, lamictal 225mg and clonazepam 0.25mg -3xday.

I take the latuda10mg, 0.25 mg clonazepam and 75mg lamictal at 7:00pm and then I take a multivitamin at 10:00pm.
It doesn't affect my sleep and I have more energy throughout the day but sometimes i feel more forgetful when i take a multivitamin vs. not taking it. But I feel I need the multi for more energy to get through the day since all of my meds are "downers".
Could there be a slight interaction here or maybe its just psychological because I am definitely obsessive and have high anxiety. Any thoughts? Thank you
