For me it sure did. Mainly because it either turned me into a zombie or knocked me out cold.
My orginal dosage instructions were: At bedtime, break a 1mg pill in half. Take one half. If not asleep within 15 minutes, take the other half.

We worked with this because on top of the 2050mg of depakote I also took at bedtime, I'd wake up after sleeping through several hours of alarms feeling hungover.
Eventually got to taking .25mg (1/4mg) as needed for extreme agitation and/or uncontrolled/racing thoughts.

Sounds like you are already taking quite a bit more than I ever did, so maybe risperdal isn't the right drug for you. Def. something to go over with you p-doc as everyone reacts to drugs differently. We are a prime example of that.

Best wishes and good luck
